Ok. Here goes..

With my PFC in the car it strats up fine but then stumbles around and wont rev up right. With all these mods and the stock computer it revs fine!!! WTF?! Do i really have 850 seconds? That the only thing I can think of.. wtf?!?!?!

I am running:

Street ported motor
3' Downpipe
3' Midpipe
3.75' Catback
Greddy Pulleys
Pettit Cold Air Intake
Full Non-Seq Twins
Removed OMP, AWS, EGR, etc etc..
Apexi Power FC Standalone with Commander
Walbro 255lph Fuel Pump
850cc injectors x 4 [I think]

Did you do the pin pulling or wire cutting? Thats all I can think of. See here for how-to http://westpenn.rx-7.org/ApexiPFCpinout.htm

Also, I assume you meant 850cc primaries, since the stock secondaries are 850cc.
