DSM Gearheads I NEED YOUR HELP!!!!!!!!!

i have a 90 Eclipse GSX and i just put a ACT 2600 clutch in it but the car still wont pull past 2500...it still feels like the clutch is slipping and the car starts to buck. Anyone have any ideas about what could be wrong feel free to drop me some help.

boost leak or bad plugs/wires. do you have a real boost guage installed? the stock one isnt worth crap.

by not pulling do you mean, not gaining speed but rpms are going up, or just not gaining the accel you thought you would have?
If its the first one, it can take about 30 to 40 normal starts to get the clutch to seat right. That or it could be oily. Process of elimination, (cheapest and easiest first, expensive and gutwrenching last) ya gotta do it.

Ok I asked one of my instructors at school oh is a Tech A. He drove my car and said that it was the fuel pump cutting out. I since then replaced the fuel pump with a new Walbro 2550 pump I also replace the filter in the process and let me tell you , My god was that thing wrecked. Anyways this helped the problem some what.
Another question of mine is what else could be causeing the fuel cut issue? I also own a Toyota Supra Turbo and I know when you are getting more then 10 psi of boost the fuel cuts due to a bad mass air flow meter. Do eclipses' have a simular problem?
to answer you back , I do have an aftermarket boost gauge made by Autometer. so that isn't lieing to me. I'm pushing about 6-8psi. HELP!!!! please
