okay... its an 87-88 vert with a 91 motor, 88 upper intake, 88 electronics. 550 p 750 seconds with a electonic oil metering pump. thats not even plugged in cause the 88 harness.. so do i have to get a 87 88 turbo front cap and mechanical oil metering pump,,, or will the power fc fix it all?
i also have the apexi 2 air fuel converter.. my car feels like its got a boat tied to the back of it when i get on it.... so ive been taking it easyy.. when i go into boost and it hits 10lbs it feels like 5 and its not a clean pull it breaks up after 5 grand if im on it... and if i half throttle it it responds better

 

This thread is old but i should say that if any of you find yourself in this position you need to find a tuner who knows their way around a rotary.

ASAP.

 

Revival, wow, 2 years old.
