I have a t3/to4b, revhard manifold, tial 38 wastegate set at 7 pounds with a hallman boost controller... My problem is that I hit about 9 psi and car tharts to sputters but I don't want it to hit 9. What could be wrong No vacuum leaks at all. Any help would be appreciated. Thanks

 

boost controller bad? w'g?

 

detonation

 

id check to make sure all of your vacume sources are good and that you dont have a f"ed up wg

 

i had the deltagate and an turbo smart boost controller b4 and boosted like 10 and so i swapped the tial wg and the hallman boostcontroller... and i have very few vacuum lines and checked, the all seem fine.

 

Ah, maybe its your fuel managment?! Whatcha runnnin? You may need more fuel to compensate for the more air/psi... sounds like a f*cked up a/f ratio

 

agreed. you need to know your afr. before tuning, my car used to sputter on the highway cruising at 130kph because it was really rich.

 

This post makes no sense. You hit 9 psi but don't want to? Well, what do you want?

 

to run 7 PSI

 

You need to run 15+
