Loose power at 90 mph
 
ive got a 91 turbo II, 0-60 in 5 secs or less easily. Rebuilt motor, i got a problem, i hit 90 quick as shit, but when it start to pass that my turbo is kickin but im not pushing any power, im accelerating at a much slower pace than i should. Anyone have some suggestions? Maybe a computer chip to stop the fuel cutt off when my turbo hits 10lbs presssure??? dunno what todo.

do you have an FCD?? FUEL CUT DEFENSER?... if so that can be it

$5 says you're hitting fuel cut. That is bad. The ECU cuts fuel to the rear rotor. Get a Racing Beat Fuel Cut Defender, and that should fix you right up!!

yeah but i heard that the fcd will cut the fuel and can also cause detonation without a computer upgrade.

hmmm...
 
but you can "feel" fuel cut off right? like a hard hesitation/bucking?

right?

If you just lose power without it shutting down, then my 5 bucks is on detonation.

im gonna get a chip for the fuel cutoff, figure that will solve my problem. we will see =)
