With the old suspension setup and before the weight reduction it went 10.9 @ 125 with a 1.67 60' with the small turbo (76/64) @ 14 psi and 3" exhaust. Since then I put a bigger turbo (80/77.5) and full 4" on it and it breathes so much better. I have no doubt it would've ran mid 10's at 15psi the way it was. Now with the suspension setup and weight reduction i would imagine low 10's on 15-16 psi and my goal is 9's with the stock 5.3 and current turbo. It should do it with around 750-775 rwhp which should be about 20-23 psi.
