1990 GTU 6 port Turbo 283hp/217tq 12psi.
To give others an idea i'll share my findings... Dyno cutoff was set for 7200. I need that closer to 8K as the car was still building power.

Thanks! my guess was 290 so its not far off! The car has never been dyno tuned only street tuned for the last 7000 miles or so and a few out of state trips to the mountains and back. Id love to have the map tweaked here and there and also alter timing a bit to be less conservative but otherwise it's a super fun car to drive. With cold AC too! If i could edge closer to 300 wheel HP with 15psi running Ethanol , but honestly I don't wanna push to far on the stock 6 port internals, especially being 9.7 rotors.

I'd keep it simple, with AC and in stock form otherwise you can really enjoy the car for what it is. Don't be blinded by chasing high HP.

i think you'd enjoy it more if you could squeeze more tq out instead of going for 300 on that dyno, going to 8krpm will probably net you that last 17hp anyway!
