hi gus well im back again

now my problem is i did fit a turbo t76 costum sts kit ( used for 1 month )

its in perfect condition on my friend's car now i did tune the car and dyno it it produced only 255 rwhp!!!!! when i drove my friend car with this kit dam it was so powerfull we did raped an jeep srt with this kit .

but now i dont think i can kick a gmc denali !!!

some will say the turbo has a problem but no sign of smoke or any issue .

the engine is still new 2007 model no issue we did check it with the hp tune no problems !!!!

the tuner is the same that tuned my friend car before !!!

i dont know what the hell is going on ???? no check engine no smoke no nothing !!!

ohhh the boost is 5 p.s.i with stock feul pump and stock feul regulator and stock injector .

 

255rwhp is what a stock truck will put down. You sure you have it hooked up right? Got any pics?

 

Was the dyno calibrated. Can you post the tune

 

How much timing? AFR? We need to know some specifics since that's a pretty low number. Dyno info would help too.

 

Sounds like the turbo air inlet isn't hooked up to the engine.

That's not a good thing unless your only going to run it to about 4000 rpm!

 

Is there a turbo wheel in the turbo... ????

Thinking the same thing here about the injectors.

 

If you suddenly lost power I'd check one of your compressor tubes from the turbo to the intake and check for a coupler loose.

 

His stockers should be good for 400FWHP
