    • Horsepower Freaks (HPF) Stage 2 with a Precision 6766 turbo hits 692 rear wheel horsepower at 15psi on stock internals

      Yes, you read it right. 692rwhp with an HPF Stage 2 running AEM. We swapped in the new Precision 6766 turbo and turned the boost up from 13psi to 15psi on Gus's brutal M3. This car has quite a bit of weight removed and has an amazing powerband. It pulls so hard and so clean. The torque is almost perfectly flat to red-line which makes driving it so amazing. This is the perfect track powerband. Gus has the ECU unlocked so he can make any changes he wants and do datalogging himself. Enjoy Gus.

        nope. no warranty on the 15psi tune.

        Wait what? A thicker head gasket was used?

        I think so because stock internals can't stand so high pressure.
        Pistons are to weak for 15psi and iff pistons give up there will be increase pressure via vacum breather and oil leakage.
