I know some commenters say you took too long to say what needed to be said, but walking your viewers through the diagnostic process was not only educational but a testament to your ability to interpret and diagnose complex problems. Specialists like you are who I would choose to bring any and all of my most expensive and high performance Vehicles to, just found your channel, subscribed!
Im here because of Alex (LSC) and I have to say, OJ you deserve way more followers. Explaining not only what you are doing but also why is infinitely helpful. Also, those shirt seams are hanging on for dear life.
Awesome video, curious about the customer's reaction. Looking forward to more content, love the analytical approach to troubleshooting and the rationale behind each step.
Very cool video! I'm sure your customer will be happy with the results of the work you did. I'm glad you are the professionals that you are. You probably saved this client tens of thousands of dollars; and now, they have a gorgeous Z06 Vette that can live up to it's reputation. Great job, OJ!
I love your videos man. But I have to tell you. The throttle closing is an issue with the ECM side of the tuning, not the trans side. Fuel dropping dropping only on the high side is indicative of too much WOT fuel demanded through the current tune. FYI, lots of these LT4s start to develop an ignition like misfire at WOT with anything under 12.00 AFR at WOT because of the direct injection. If you need help with the throttle closure and drivability of this car, message me. 😉
Thanks. Still here from Alex. Love to know the customer reaction. Think i would be delighted. Don't forget the air leak and plugs all making it sweeter to drive. I hate throwing new items in without being more sure but you nailed it.
I have much respect for you. I personally don’t need to be told things over and over. Maybe you didn’t have enough content and that was a way to create more.
Tuning is definitely an art, that's why real speed shops mostly tune specific vehicles and even the best performance shop needs a real tuner to get the job done.
36:36 One of the weirdest modifications I found on a vehicle was a 1965 F250 I got for a screaming good deal. It was in really good condition and ran great, but the battery would go dead overnight. I thought the wiring on a 1965 truck should be simple, so I started working on it. I pulled so much excess wire out of that truck that I filled a 20-gallon trash can. I removed 5 sepeate trailer wire harnesses. It had the stock brake light switch on the master cylinder, plus 2 more switches added to the pedal. There was a single under hood light powered with literally 50' of #10 wire that was wrapped around the steering column to the fan motor and back instead of cutting it to length. It was insane. The problem turned out to be a bad regulator, but it took hours to remove all 5 miles of extra wire just to get to the point I could troubleshoot.
Do we like automotive detective work? We love it! Just like all the "true crime" that's catching on on Netflix. I'm sure we can find the weirdest faults with all the kinds of cars coming in your workshop.
This episode reminds me of Jeremy at Fasterproms and his problem solving and tuning.People don’t realize that on performance tires the softer the rubber the more brittle it gets in colder temperatures. Now winter tires are designed to withstand the cold temperatures and stay soft.
I dont mind the longer video. You cut out installing the new fuel pump, going back on the dyno... I think its very well edited. All there really is left to cut out is your commentary, none of which i think needs to be removed. Not everything needs to be 20 min. Keep up the great work and i love the overall look and feel of your videos I went to school for these things, so you can trust me 🙃
Im glad you didnt just follow the customers idea of going back to stock, which costs a lot, and challenged yourself to make what was there work and fix a faulty part along the way! Tuning sometimes comes easy, but with an unknown bad part, things slow way down and you have to monitor everything. Nice work. Hopefully others learn to not give up as it ultimately isnt in their best interest vs solving the real problems, except for raising value for a stock vehicle/sale situation. Biggest problem could be the time the customer has to sort the issue(daily driver) and finding someone who can efficiently and effectively fix the problem.
You know maybe if id found a shop like this id stayed in the field. Im a ex ASE certified, coding/computer trained tech who walked away in 2010s due to pay/vs skills required. Yeah a parts swapper may be worth todays Tech wage wage, but i gotta be a mechanical expert , a computer expert to truley diagnose and fix cars today. That deserves a GOOD HIGH living wage. Commercial carpenter now(high rises bridges) happier healthier and wealthier. But i do miss fixing stuff that 2+ shops couldnt fix. Customers alwats loved that. I really enjoyed proving the "oh itll never work" ppl wrong
I had many tuned-port-injection 350s that were detuned from the factory in the late 80s and early 90s ... just balancing the injectors made an instant difference in power - and the TPI upper intake seemed like it was purposely chaotic inside ... smooth polished intake runners really woke them up
As somebody who's been a tech probably since you were in grade school and works on a lot of modded cars. My guess is someone built this car, maybe a shop but when it didn't run right they assumed that all the parts they'd just installed including the fuel pump that came with car worked (HECK SOMEBODY PROBALLY DROPPED IT) or it was just going bad like it was an Audi pump . Then they tuned until it ran OK , called it good sold the car and moved on. It's an oddly familiar story that involved a 911s.
Tuning and modifying cars is a crazy game. Regarding supporting mods, I have said to myself many times "Nah, I don't really need it right now" and every time, I toss and turn in bed until I finally pony up and buy that part. In this case of the customer refusing the TCU tune to support his ECU tune, I give it a week before he decides yes, he wants his TCU tuned as well, lol.
My tires came with a warning of don’t do anything that would change the shape of the tires if the temp is below 20 until they reach 40 again or you may damage the tires.
O.J. You mentioned the TCU being in charge of closing the throttle at the top end and the customer declining additional work to address that. Can you provide more information on that? What would be needed to address that, would you be able to see more gains, what the costs might be, and would if affect drivability(or would it just be something you see on the dyno/track). Great episode! Really love the detective work and seeing a car put right by great mechanic work.
All the new gm cars have funky torque tables to try to keep the Trans alive. He shld have ponied up for trans tune. I think it's only 1 more credit and 1 for HPFP
@jplperformance9073 oh so it would have just been more tuning? ("Just" I know tuning can be almost as much of an art as it is science at times). I was wondering if it was further modding or part swapping e.t.c. Thanks for the response random internet stranger!
Definitely more gains hp and drivab ability imo. Yes more tuning. Hp tuners is 100 bucks a credit. Cld be 2 to who knows what some of these newer cars, credits to tune.
Cool video man. But throttle closure is 110% ECU tune related. TCU torque limits are completely controllable through the ECU tune. LT4’s also being DI, absolutely HATE being as rich as you’re running that with it pouring black smoke into the cell, AFR in the low 11’s is the best way to turn the bores into a mirror and kill them. Really need to be 12.0-12.3 AFR with a DI car at low boost like that to give it a clean burn. 580rwhp is stock pulley stock cam exhaust+tune numbers so definitely could do with some refinement in the tuning department, but it’s on the right track. Love seeing the exhaust stuff you guys do.
The top performance diesel guys have found the better spot for making traction on the dyno is on the front of the roller. The geometry of the straps are giving slack as the tire is climbing . Vs the strap is gettting tighter as the tire trys to lift the roller.
Are hub dyno's a luxury compared to rollers? Just seems they might solve some of the torque and strap down headache's with room for higher power vehicles.
So the owner was willing to spend $10K+ to take the car back to stock but wasn't willing to spend less $ overall to get a full tune that included the trans?
Funny, that HPFP looks just like the LT1 pump I pulled off my LT1 C7 that I upgraded to LT4 HPFP. The inlet tube is centered on the lt1 pump and offset low on the lt4 from my experience. Looks like they had the wrong pump on it. What part number is on that removed pump?
Thank you so much for this amazing video! I need some advice: My OKX wallet holds some USDT, and I have the seed phrase. (mistake turkey blossom warfare blade until bachelor fall squeeze today flee guitar). What's the best way to send them to Binance?
I have a 2002 Olds Intrigue. It produces about 215 hp, but I modified the air intake box to let in more air and it accelerates more quickly now. The inlet to the air box was literally 1/2 in away from the back of the flat surface of the headlight. I cut away part of the inlet to let in more air and it seems to work. Do manufacturers do simply things like this to limit the hp purposefully? What do you think 🤔? Thank you!
I have to tune out my CEL on my camaro to get it to go away. Short tubes with highflow cats triggered the CEL. Everything is running great and my gas mileage is good and it doesn't smell like its running rich but im still going to dig around a little more just in case before i tune out the CEL
Before i watch and knowing it has been modified id guess that the oem computer likely wasn't tuned therfore it is pulling timing when it sees much greater than oem boost pressures?
My un-modded 2019 ZO6, has had an issue since about 2000 miles. It sometimes idles rough, and active rev-match causes a misfire, unless it’s been run hard. Two injectors were replaced under warranty, but that did not fix the problem. Now at 20K miles. Checked plugs, wires, coil packs. Very frustrating.
Here from Alex's channel. Like the content but needs a little polishing. I know it's new to you but I recommend watching some other really popular channels how they deliver content as well as even Stacy David as much as I hate to say so with his hair worse than yours, no offense. Alex is really good at explaining everything he does, in terms that novices as well as regular wrenchers can appreciate. I enjoy the car work and the sleuthing. I'd like have a little better explanation of some of the terms even though you explain some of them later but some of the acronyms I was unfamiliar with because I haven't worked on high pressure fuel systems. Even though I wanted more explanation on some things there were some parts that could use some condensing, the intro was a little long-winded and could have been probably knocked down a bit and still gotten the point across. Also it would have been kind of cool to see a reaction of the client to his car after being changed. Reactions are always popular with videos. Just a couple tips. Hope you succeed, I'll keep watching. The more shows you do the better you'll get I'm sure. Anyway I liked and subbed to help out so keep at it. I know you got the skills to do the car work.
I'm sure I'm not the first one saying this but I lost interest in looking though the first 20 comments to find out. A modified C7 Zo6 Vette putting down 430hp is absolutely ridiculous. My 2012 GS with just intake headers, catted Xpipe and a tune produced 420hp/420tq. That was on a Mustang dyno that traditionally records at least 10% lower than a traditional dyno. Given the seat of the pants feel, it's definitely faster than my supercharged 2019 Bullitt.
im having flashbacks to subaru owners putting bovs on their car then getting check engine lights for running rich because they're blowing off metered air. it was always the shops fault. we can remove the bov or install a standalone. they rarely picked the stand alone
That horsepower is a little bit more than what they come stock. With the pulley and the other modifications he has to the engine I was expecting well over 600. Do you think the TCU is now the restricting factor?
This car definitely seems to still be down on power…My 2016 stock C7Z made 594 at the wheel with just a tune. Now Im making 680 at the wheel with only a ported stock blower, 2.5 upper pulley, CAI, and headers.
Not a discovery, but in an effort to drop rpms quickly when shifting, racing only, i have the IAC on a switch. With the IAC closed, the rpms drop like a rock to aid the shift. Also drilled a small hole in the gas cap bc the gas tank was pulling a vacuum (tank thunked after shutting car off) and was causing fueling/drivability issues, resolved after the hole was made. Probably need a new cap but wanted the issue solved permanently. I hope i dont flip my car, its street car. I turned off the "remove fuel on decel" feature in the stock computer map so now the car coasts in gear (5 spd) rather than the engine trying to brake and slow the car.

great detective content i like it your channel is my morning coffee with legit street cars :)
Same
lol considering LSC makes this look like motor trend from 20yrs ago.
Me to from Normandy France ❤
Great video. I love the detective aspect of your diagnosis segments. Keep them coming.
Woohoo!!! I’m excited for a new episode! Thank you for kicking butt as always !
A drive on performance tires in 16 degrees weather is a recipe for a sketchy time!
Reminds me that I've got a set of r888r sitting in my shed with an upcoming low of -6 this week. Maybe I should move them... 💀
@@jakef.9526or keep them, divorce your wife and move to a warmer climate.
Actual diagnostic auto repair is getting rare but is not lost, clearly. Bravo all, great content with very high production quality.

That was very interesting O.J.! You had me glued to the monitor.
I am so invested in your vlogs. CSI on a Z06! BADASS.
You’re finding your flow man!
Great work, I look forward to many more videos from you.

Interesting case study and quality diagnostic. I think the Stingray make make around 409 WHP but not a Z06

Love seeing the exhaust stuff you guys do.
great disgnostic
would a hub dyno be more appropiate ? no suspension lift or wheel slip?
Great video!! I may be bias because I own the same car.
Absolutely enjoyed it.
I probably missed it, is there a dyno chart of the fuel after the Hi pressure fuel pump replacement?
Easy thumbs up 👍🏻 💯
Correct me in I’m wrong but isn’t 580~ stock wheel power numbers on a c7 z06?
Around 520ish unfortunately.
Your customer made a great decision on bringing to your shop
The top performance diesel guys have found the better spot for making traction on the dyno is on the front of the roller. The geometry of the straps are giving slack as the tire is climbing . Vs the strap is gettting tighter as the tire trys to lift the roller.
You should have brc race works brian cunning ham remote tune it for you i have a dyno dynamics dyno too and hes done a couple cars for us remotely
Are hub dyno's a luxury compared to rollers? Just seems they might solve some of the torque and strap down headache's with room for higher power vehicles.
Simple mods on these(LT4) make pretty good power, just 50% E85 on my Zl1 produced 634RWHP (Dynojet/SAE).
I think his dyno reads a little low also or it could be that the TCM tune was stock. That car should be making 600rwhp on 93
when we say let the car cool down are we talking down to 160f coolant temp or normal operating temp?
love the video- you need better lighting!!!!!- looks like a shop in gothem city lol
So the owner was willing to spend $10K+ to take the car back to stock but wasn't willing to spend less $ overall to get a full tune that included the trans?
Funny, that HPFP looks just like the LT1 pump I pulled off my LT1 C7 that I upgraded to LT4 HPFP. The inlet tube is centered on the lt1 pump and offset low on the lt4 from my experience. Looks like they had the wrong pump on it. What part number is on that removed pump?
10:35 Weld a few places straps can be connected to the frame of the Dino. Seen other channel do it. This way it pulls the car straight down.
starting to plug fuel filter would starve delivery as well unless one can log pre filter pressure
Thank you so much for this amazing video! I need some advice: My OKX wallet holds some USDT, and I have the seed phrase. (mistake turkey blossom warfare blade until bachelor fall squeeze today flee guitar). What's the best way to send them to Binance?
Great video. Maybe turn up the dyno audio.
How much bigger is the cam fuel pump lobe. A bigger fuel lobe requires software adjustment.
My experience with "fixes" involving cleaning never fix the issue because either the part just needs to be replaced or the part is not the cause.
maybe the most exhausting video I ever watched
my old company CEo would drive his Z06 in when it was raining, said traction control is his right foot
wish yall had a shop in central florida !!!!
I have a 2002 Olds Intrigue. It produces about 215 hp, but I modified the air intake box to let in more air and it accelerates more quickly now. The inlet to the air box was literally 1/2 in away from the back of the flat surface of the headlight. I cut away part of the inlet to let in more air and it seems to work.
Do manufacturers do simply things like this to limit the hp purposefully? What do you think 🤔? Thank you!
2019 car with a 2016< supercharger lid? - Would have been asking questions myself.
I have to tune out my CEL on my camaro to get it to go away. Short tubes with highflow cats triggered the CEL. Everything is running great and my gas mileage is good and it doesn't smell like its running rich but im still going to dig around a little more just in case before i tune out the CEL
I like what you said trust your gut if it feels wrong, it probably is
What in the windows vista / 7 is going on with the Dyno PC?
Before i watch and knowing it has been modified id guess that the oem computer likely wasn't tuned therfore it is pulling timing when it sees much greater than oem boost pressures?
Alternate video title: "Turned down for what?!"
My un-modded 2019 ZO6, has had an issue since about 2000 miles. It sometimes idles rough, and active rev-match causes a misfire, unless it’s been run hard. Two injectors were replaced under warranty, but that did not fix the problem. Now at 20K miles. Checked plugs, wires, coil packs. Very frustrating.
Dyno numbers seem really low for a modified LT4. What brand dyno?
I found someone installed a resistor bridge instead of a knock sensor. Lots of pinging/knock…

A modified C7 Zo6 Vette putting down 430hp is absolutely ridiculous. My 2012 GS with just intake headers, catted Xpipe and a tune produced 420hp/420tq. That was on a Mustang dyno that traditionally records at least 10% lower than a traditional dyno.
Given the seat of the pants feel, it's definitely faster than my supercharged 2019 Bullitt.
Kicking ass guys
u the man man
im having flashbacks to subaru owners putting bovs on their car then getting check engine lights for running rich because they're blowing off metered air. it was always the shops fault. we can remove the bov or install a standalone. they rarely picked the stand alone
great......
Awesome
That horsepower is a little bit more than what they come stock. With the pulley and the other modifications he has to the engine I was expecting well over 600. Do you think the TCU is now the restricting factor?
Knew there was a big difference when he started the pull and smoked the tires on the dyno
Is that the z06 with the wrong engine in it or another one?
If it's a 19 it's the wrong motor. It has the 18/19 hood liner so I'm guessing the guy he bought it from threw an older motor in it.
This car definitely seems to still be down on power…My 2016 stock C7Z made 594 at the wheel with just a tune. Now Im making 680 at the wheel with only a ported stock blower, 2.5 upper pulley, CAI, and headers.
30:31 a base C7 does 430RWHP a dyno jet. Z should be around 550
He said c7z usually make 485 on HIS dyno
At what time stamp did he say that? 30:31 he said in the 430 range for c7z
Not a discovery, but in an effort to drop rpms quickly when shifting, racing only, i have the IAC on a switch. With the IAC closed, the rpms drop like a rock to aid the shift. Also drilled a small hole in the gas cap bc the gas tank was pulling a vacuum (tank thunked after shutting car off) and was causing fueling/drivability issues, resolved after the hole was made. Probably need a new cap but wanted the issue solved permanently. I hope i dont flip my car, its street car.
I turned off the "remove fuel on decel" feature in the stock computer map so now the car coasts in gear (5 spd) rather than the engine trying to brake and slow the car.
@FluidMotorUnion Who tunes your cars for you? I have a C7 Z06 I'd love to get ironed out
I’ve seen a modded car drop a full second in the 1/4 from a shady tuner to a real tuner. A tune can definitely make or break a build
OJ is the mechanic that you hope you get. The tuning game is nothing like it was. You need a pro.
Cya all day!
