ok, i have a s14se with a s14 black top sr. gt2871r,megan mani, dp, and turbo elbow. turbosmart bov, fmic, and so on.

my car was running great no problems at all, but the ic piping was homemade and looked like crap, so i pulled it off, cleaned it up and went to drive the car.. it wouldnt go into boost, as soon as the it reads 0 psi and tries to go over it will just fall on its face and sputter, all while not going any faster. so i thought it was a boost leak and bought an ic piping kit with new couplers and all., i also tucked the harness over the intake mani. the car sat a couple days, and when i went to start it and drive it. it still does the same thing. i have checked all the couplers and piping. no leaks. i am not sure what to check next. someone help me out here.

UPDATE***. ok, today we checked all the wiring, checked the maf, checked for boost leaks again, and checked the coil pack/ignitors. everything was fine. what else could it be.
