I agree though that you are outside of that turbos efficiency range with the car.
Slap a 80-85mm T6 on that thing and let it eat.
We tested the smaller and bigger housings for this turbo. The smallest 84 Trim 1.01 A/R choked out way to early. The 84 Trim 1.28 A/R was way to laggy. So it was decided to stay in the middle with the 84 Trim 1.15 A/R. I completely agree with you guys that a larger frame turbo would make more power but I really don't wanna spend the money on a new unit and the kit was built around this very expensive turbo ( size wise ). I really think I can get into the 9s with this turbo. I also agree that going from 15 up to ~20, i will drop the HP/PSI. Right now its around 29hp/psi.

Its been a while so, I updated my map. Ill also post the dyno sheet so you can see the power band.
