hey guys got 2 seperate problems and in need a bit of help
car is a 32 4door 20det,major things; hks cams, blitz turbo, rising rate fuel pressure reg, standard bov, fmic, exhaust, boost tee, standard ecu, aftermarket fuel pump (not sure on brand) PROBLEM 1: Im under the throttle little bit hard. Put clutch in and let revs drop, it basically just stalls.. or drops down to like 300revs then will all of a sudden pick up? But some times randomly like today in stop start traffic it would sometimes stall, even in neutral, highway driving etc. is fine its just when coming to a basic complete stop!! PROBLEM 2: boost will stay around 0.5 bar, sorta hard to explain but was looking at the turbo and line that goes from actuator to boost tee then boost tee back to a nipple thats on the turbo?? thats not right is it?? so i unplugged the line that goes from the tee to actuator so it would free boost, went around the block, turbo is alot noisier now (spooling harder etc.) seems to pull a bit harder but still stayed around that 0.5 bar mark ive tryed my best to explain to it!! PLEASE HELP!!! josh --------------------  |

Problem 1 sounds like an AAC issue.
Problem 2 - don't EVER disconnect the hose from the wastegate actuator. I don't care what the gauge says, you will be building enormous boost levels because the wastegate will not open. It sounds like the hosing is correct - I'm guessing the tee is to a bleed-off valve. -------------------- STRESS - the confusing emotion created when the mind overrides the body's basic desire to bash the crap out of some jumped up little turkey who's been asking for a knee in the cobblers for the last six months
