ok, so my fc was runing fine untill llast week when i started feeling th3 3-4k hesitation. thought it was normal so just wating to get ground wires. but now it hesitates like crazy at unexpected times. usually under mild to heavy acceleration. Ive never driven another FC so i dont know if what i am experiencing is hesitation or not; but i will accelerate, and anywhere from 2-5k ithe engine will feel like its about to die and bog.
also when this happens, usually when i start on a hill in 1st gear, it will do its little "im gonna die on you" thing so i have no power, then whn everythign goes back to normal... SWEEEEEEEEEEEEEE! full boost in double time. its funny because ever since it did it's hesitation thing ive noticed a decrease in turbo efficiency.

pleez help me on this because i dont really know what is wrong unless grounding makes a really big difference.

the only engine mod is a turbo back exhaust, hi-flow cats, and a bov.

 

I'd check your TPS sensor at the ECU. Mine was doing the same thing, and suffered from a crappy idle, but that took care of it.

Run a search on TPS adjustment, and get the ECU pinout from the FSM for your car.

 

second that.. sounds like its getting to much fuel
