I installed a to4e hybird yesterday I am getting about 5 psi I have a greddy P.E. exhaust, no cats, bonez downpipe, Walboro 255, 720 secondarys, Rteck 1.7 chip Safc, FMIC I was getting about 7 psi with stock turbo, I am using the stock TID is this the reason for low boost ? I pressure checked piping and intercooler checked OK, I tried to test pipe, turbo, and TID but it wouldnt build pressure is it suppose to be able to hold pressure?


Thanks Johny

 

tell me you have some sort of boost controller . if not you should to get one .
i have a very similar setup and yes i did run without it for a while when it was fairly low like at 7lbs boost but i did have boost spike which is NOT GOOD. i think stock boost should be 7 so you should be seeing 7lbs . the club is having a group buy on widebands i suggest you get your hands on 1 so you can tune your 7 with it since you hace an AFC . regular a/f guages are not accurate especially if you plan on running higher boost . i will be running the wideband full time that way the correct A/F reading is always present .
try to get a ebc or a mbc if you can .
