so after about 3 months i have my cefiro running again, so current spec's are set of custom grind cams, gt35r turbo running 7psi to 3 inch reducer to use afm (untill i get the money to get the ems fitted up) forward facing plenum with 4 inch throttle body, 3 inch turbo back exhaust, 38psi fuel pressure with a walbro 255 intank pump.

current issue is under load it will hunt chug and not want to rev, have set the tps up with .5 closed 4.1 open.

free reving it it will rev fine all the way to the liminter, some times it gets a small flat spot but you can rev through that.

im wondering if

a) afm is to close to turbo????? is about a foot away from the intake but it was doing this before when it was 2 foot away from it.

b) injectors are full of rust and shit from sitting for so long.

c) i do have a air leak at the manafold to head but carnt see it causing it miss this bad.

cheers tim, just need the car to run good for the week while the other vehicle is getting fixed
