No shit I came to the comments just for this too you could here the engine hunting for rpm ! They fucked something up bad!!! 😂 probably tune! I can't believe they thought that was normal 😂these guys lost my respect 😂
To get a stock computer to work without the hooked in the vehicle you need to start the engine and run it and while it's running disconnect the body computer let it run for 15 minutes without it shut it off and try to start it if it starts then the computer adjusted itself to run without the body computer if not repeat till it does
They have all those tools and a shop plus the cost of a tune....Just go to blueprint engines, dial in your specs and they'll build it from the ground up, dyno your engine and ship to you. the cost is 3-4K but all the work is proven!! Just a thought. I know I love turning wrenches but time is money
About to get a 08 trailblazer ss with the 6.0 ls2. Heard the engine has its flaws so I’m I want to go with a different set up. Anyone know what good engine to go with? Heard people talk about the iron block 6.0 lq4 being more reliable and putting down more power. Anyone know what’s the right way to go?
They’re both good but you already have an LS2 with better rods and pistons than most LQ4s. I’m building an LQ4 with forged rods and pistons, machine work, bearings, studs, rings, gaskets etc, etc, etc for about 3500.00 before topend. You have a good engine just do heads,cam,intake and you’ll be happy with more power and more money in your pocket.
I thought the same thing too, until he mentioned the trunions were 1.82 ratio. Instead of the factory 1.7 the bigger ratio makes up for the small cam, I guess?
Since you guys had a oil pressure issue, I am surprise you didn't go with a cheap but necessary fix (bolt on retainer) as used in this video th-cam.com/video/gD7gQLSLMTM/w-d-xo.html
Thank you! That dip in the middle shows the engine laying over and then picking back up! Just comparing the before and after, tells you something not right.
I just realized their numbers are BS old style gross horsepower numbers cuz they don't run a full accessory drive like the oems have to run for a net horsepower rating
If you watch any of Richard Holdener's videos, he explains that most engine dyno horsepower numbers are not extremely accurate and are usually best case scenario. They usually don't run any belt driven accessories, they use dyno headers, electric water pumps and play with the tune for best ignition timing and fueling. Actually I think David Freiburger tested parasitic loss from belt driven accessories on Engine Masters. I was quite surprised at just how much power is "robbed" to turn certain accessories.
TAKE MY MONEY!! I want this on my 05 Denali XL. Not to race, just to cruise, fast. Lol
Same, but on my 04
That dyno curve looked like a damn mountain range wtf
Thank you! That graph didn't look smooth at all! That's why those mail away tunes are hit and miss.
I came to the comments just for that. It was horrible. And for only 25 hp at the very top end? I'll pass. It was a lot better before.

58👍's up gunpowder and gasoline thanks again for taking the time for us all to be with you
I trued my lq4 6L in to a 6.7L i I added 44 cubic inches to my 6 l

If they tune them there they could just delete the VATS
Holy crap that thing needs real tuning work BAD! That huge dip right in the midrange would drive like absolute crap.
I hate to tell you guys but you spend well over your budget of $2000, counting the price of the lq4.

Not sure what flaws you’ve heard, but the LS2 is a pretty legit performer and reliable akin to any other LS.

@@deegan727 Can you tell me how the LQ4 went and how much it costs with everything done and over with? I'm interested in suping up my LQ4
LQ4 just has a IRON block, they are both the same, nothing wrong with either. your hearing to much internet folk lore.
Friend of mine buys and sells LS and says aluminum blocks are shit.
That was a pisspoor tune
Mail order tunes are hit or miss!
Don't we want to grease the ends of our pushrods?
What rockers are those
Summit Racing SUM-141556 - Summit Racing® Pro LS Upgraded Rocker Arms
Time for a better tuner
That’s a baby cam for a 6.0.

That was a shitty looking Dyno graph

Everybody does that

That curve was ugly
It needs lots of work.
@@billl7551 definitely.
Definitely some issues there. HP took a straight dip then shot back up!
