Question 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 ****, 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.

$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.

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