Hello guys!
I've just recently finished building my engine. I believe i am having a low boost issue. I'm only getting 7 psi @ WOT with my 2.55" pulley. I have a new BBV and don't have any vacuum leaks. I noticed that i had a large exhaust leak right where the EGR meets with the neck on the ZZP header. The EGR hole in the blower case is filled in. I just had the EGR on as a decoy. Would that cause 02 conflict and or loss of boost? The sensor is about 6" away from the leak. The car certainly hauls ass with the 7psi it has though. Fuel trims are good, no KR.
My Build:
ZZP Ported Gen3 Blower
ZZP 78mm TB
ZZP Ported LIM
ZZP CNC Ported Heads
ZZP Stainless Headers
ZZP Tune
ZZP Stage 2 Intercooler
ZZP Short block with 9.4:1 Compression
LQ4 MAF
#42 Injectors
XP Cam
Fully built 4340 tranny 3.29's, 2500 stall.
Comp Cams OER Lifters
Cometic 0.052" Head Gaskets
2.55" Pulley
Thanks for the help!!!:th_winking:
