Really good video. I had a bad tune before and now have a good tune. It’s night and day difference. My problem with the previous tuner was the throttle issue. All the power was in the first 20% of the throttle. It would boost to 10-12 psi over and over again for no reason going down interstate on flat ground and gas mileage obviously sucked.Y’all seem like guys who know what you’re doing. Thanks for making good reliable tunes for people!
Excellent information here! Nicely presented, thank you!
Great video and information thanks
Glad it was helpful!
Thank you for a truly realistic view of tuning
Great stuff guys I just found your channel, agreed cylinder pressure can be a great way to make a truck rip the tires off but also push a head off the block as well lol. I do however have some questions about the efficiency ranges you are seeing with the stock appearing chargers vs say a borg 3xx frame charger. Hopefully I can call to discuss some thoughts and options for my 06 Cummins
Give us a shout, 815-568-7920.
Can you guys do a video of important information to look out for that the truck is trying to tell you when you read PIDs for edge an monitor. Or important values with basic readings .
That one’s on our list Austin :)
How does tow/haul mode work on a tuned vehicle? Does tow haul mode still modify transmission line pressure and shift points on top of the tune settings?
Tow/Haul works largely the same in a tuned vehicle as an un-tuned vehicle. It still modifies the shift schedule, line pressure (where applicapable), and TCC strategy. Use it!
Based on your website comparison in description of tunes on super chips
What’s your take on bully dog and edge?
Little better or about the same as super chips
We have not done any testing. I would say based on general reputation, they are all fairly close.
Do you know of a OBD Bluetooth / iPhone app combo that would act as a digital monitor and work with an L5P?
Not yet.
The tune that came on my 6.0 ps was really bad, got quality tunes and it's a whole new truck. Didn't even run that tune for a week before I reset the pcm and tcm because I hated it and had no tuner at the time
Will yall do a video on whether to or whether not to Destroked a 6.7 Cummins to 6.4 or leave at 6.7?
Leave it a 6.7L.
Just found this I have a Lbz that was tuned by some jo with a laptop haven’t really drove it at all bought it like that no coolant issues or oil issues but when I start up or after letting off the pedal in pukes white smoke like it’s a improper combustion and it’s super hazy while driving normally I know the hazy is from the tuning being to hot but could the white smoke from a improper combustion be caused from the timing in the tuning being wrong? I’ve smelled the white smoke and it’s strong but it don’t smell like raw fuel or anything I’ve ever smelled before
Best thing you can do is start eliminating variables. Check codes, solve if they exist. If you can go back stock tuning and see if the problem persists, start there. If that doesn’t help I’d be suspicious of the injectors next. Guys who cheap out on tuning usually cheap out on injectors as well. Good luck
@@Duramaxtuner it’s got new oem injectors with 100% over nozzels and a so cal stage 2 build but he assembled the motor not so cal I think I’m going to pull it and take a look at everything
Just got a smarty tuner for my truck 2000 24v today and lost 5 gear on freeway 🤯my fifth gear is neutral lol what ? now I’m im shopping for a new nv4500 instead of my calibrated 64
Sounds like your fifth gear nut fell off common issue but if you don’t hear grinding you got lucky and it fell to the bottom pull the trans and have the nut welded on and you won’t have that issue again
Yeah I increased the power on my old Toyota diesel by 30% and it sounded better, felt much better, but you only noticed a huge power gain with the tv locked up. Changed my trans a bit to where it locks up half way through 2nd gear, then stays locked through overdrive, and it decreased by 0-60 by 2 seconds. Also gained me another 2mpg.
Nice. Being around doing this for 17+ years we hear these and horror stories constantly. Glad yours is working great!
Yeah im 90% positive im the guy that bought a used LBZ with tunes installed by his buddy in a garage. EGTs run high towing/not towing cruising highway speeds
Have you boost tested the truck?
@@Duramaxtuner not yet. Just watched your boost leak vid...gonna look into that thanks. Having a tuned truck with idk whos tunes in it doesn't make me feel too comfortable while towing. Basic stock 06 LBZ
my truck smokes only when it shifts, under WOT it barely smokes, is this normal?
Besides you. Who are the other reputable tuners out there? Not just for power but for reliability also
Most of your big companies are gonna be reputable. If they wasn’t they wouldn’t be in business. People like kory Willis with ppei, Idaho rob, and the list goes one. What you don’t want is to get some random tunes from
Local shops without knowing what they use or using their tunes when they don’t have the reputation and data to back it. Also know that almost all tunes even good ones can hurt the longevity of transmission and torque converter. Smoke is hard on pistons. Just do a lot of research.
xv70 1 that is not even close to being true. Factory tuning is death on emission trucks. The big 3 do not optimize trucks because they offer warranty’s and then never back those warranty’s most of the time. If factory tuners were the best then there would have never been a market for tuning
I'm building my first diesel. I'm just putting a banks six gun in it. I trust the banks name. And I don't need to be blowing trans
@@dakotadickens3747 any thoughts about CTT? I just ordered an ezlynk with CTT for my '18 Ram and curious if im getting myself into trouble.
Austin Hamilton have zero idea on ctt but ex Lynk is nice
Buy once cry once
Big facts, I'm only 18 just bought a fucking billet cam, I wouldn't dream of having anything billet 4 years ago...
Jesus Christ I want you guys to tune my 7.3 but you don’t offer it on your site.
Is Smokey really that bad
Yes, smoke is incompetence in today’s time . There’s no excuse a diesel can’t be tuned smoke free, until you reach a certain point on fuel injector size ..
Yes! Smoke means you are wasting fuel, causing higher than necessary heat, and often it actually costs you power.
@@Duramaxtuner so your saying there is no pros to running lbf to try to get a turbo to spool faster?
@@lifted9821 Turbo spool is impacted by exhaust housing design, turbine wheel dimensions, and vane position more than by excessive exhaust flow. In most cases, you can spool a turbo just as quickly without smoke as you can with smoke. Now, if you are talking about a single s400 or similar turbo, smoke while spooling up may be inevitable. However, most of the newer, large vixed vane turbos are being designed for quicker spool-up. Thereby reducing how much smoke will be emitted at lower boost pressures.
@@Duramaxtuner thanks for the reply.
First
🍪😂
@@ToshGT35R yeeyee🤣🤣🤣
What an honor; wow!
Hard to believe that this guy runs the company. Nick comes across great but it has not been my experience when dealing with the company. Calling just rings through a bunch of ring groups without being answered. Sales person never answers post sale the phone or email. Had to trick him into calling me back. Said I would have my tune in a couple of days, it's now been 3 weeks and not once have they reached out to me to say what's going on. At this point it's been a wasted investment.
You do realize that many businesses are lucky if they have 10 percent of their staff available.....4 wheel parts is horrible right now for service. But they are down to a skeleton crew. 3 hours on hold is normal right now. Use your brain numb nuts, im sure you can do it
@@ks_1111 I would be OK with that, they have not communicated that. They set the timetables. They had time when it was payment time. There salesperson said a couple of days. It's been 3 weeks. Had they called and said there would be a delay, I would understand, they have decided not to. Monday the salesperson said I would have something by the end of the day. It's going into Friday, still nothing delivered, no email, no phone call. You have no idea what you are talking about so I am not sure why you want to be insulting. I can only imagine how you would react to someone holding $900 of yours with zero response.
@@taylorsrus9543 Shoot me an email and I will get it taken care of. paul@duramaxtuner.com
@@Duramaxtuner Thanks for getting this resolved quickly and professionally.
