whenever i'm in gear and try to smash past 6 thousand rpms, i get a massive loss of power, as if my fuel or something is cutting out. the whole car starts to shake, and i feel no accelleration whatsoever. In fact, I feel decelleration, untill i shift to the next gear up. I bought and installed the FCD, but that didn't do anything. Help me please.

 

Turbo, I am assuming. Year?, Mods?, Condition?, AMount of Boost?, Stock Fuel Pump?, Free Exhaust, or Stock? what?

 

You're hitting fuel cut... if its the HKS style FCD, you need to adjust the trimmer counter clockwise until it stops...

 

if it does it while not being in boost it's not fuel cut. i went through this not even 4 days with another guy having the same exact problem and i've had this problem myself. trust when i say: replace your TPS it's fubarred.

 

Its your TPS. mine did the SAME THING.

 

well.. i just bougt a new motor anyways, because its all old. but the fcd is a racing beat, so i dont know if i can adjust anything. i shouldn't need it though, because my car is completely stock. I'm boosting normal... i think. hey does anyone know what stock boost is for s4 turbo?
