New Exhaust But No Boost Increase?!?!?!?!?
#1
I put on a 2.5" RB DP to a resinator and exhaust shop made for me to a RB 2.5" cat-back and now im only boosting 4psi!!!! I do not have a FCD or ported waste gate, my air pump is still hooked up but its not hooked to the exhaust, I was thinking maybe boost creep or fuel cut what you guys think???
THANKS

no cats the resinator the exhaust place put on i cant see through but they said it still flows pretty good alot better then the cat, and Its almost as quiet as when I had the cats on. I have a autometer boost gauge and its reading the same as befor.

No ive seen what a resinator looks like, the are pretty much smaller halowd out cats, that wouldnt be restrictive, I think they are just to keep the noise down. Like 1revvin said about, check for boost leaks, do you hear any hissing by the turbo? I was getting at least 5psi stock in 1-2nd gear and 6-7 in 3-5th. So prob leaking, or ur turbos bad.

I found one leak the turbo inlet pipe is cracked I taped it with some high temp sillicone tape for now till i get a new one and I left the Air pump off I got 4-5 in first but it bogs down a lil at 6,000 rpms and the boost drops to 3PSI, in second its 5 PSI but bogs a lil at 6,000 RPMs. I can here what sounds like a leak behind the intercooler or down by the downpipe but cant find it tonight its to dark.
