Tomorrow is dyno day. I have been trying to get a ballpark guess of how much power it will put down.

Depending on the dyno, I think you'll be in the low 500s on both hp and tq with a lovely torque curve regardless of the numbers. Here is a good place to look for reference: https://www.youtube.com/results?sear...racecraft+gto+

Well today was interesting...
Unfortunately the 325 Aeromotive
Pump wasnt up to the task. The injectors were maxed out as well. Zr1 injectors.

Car made 527/564rwhp/tq. I started tuning rich at 10.5:1 and set timing at 10°. Couldnt go any further because of the fueling limits. And the boost curve was weird. Kinda plateaued then krept up near the end. 12-13psi.

Looks like you're going to be solid mid 500s on both hp and tq once you get your fueling issues sorted. You might even get both into high 5s with the right air. This is an M6 car, right?

10.5:1 is garbage, that thing should be 12:1-12.5:1 if you want life and power out of it.
