You will be amking max power around 5800 RPM, your optimum shift point will be about 6100 RPM. It's always best to let the car shift itself. It's pretty smart.

By the way we just dynoed a car with:

Needswings CAI
178 mm Pulley
Custom Tune

It layed down 320 RWHP on a Mustand Dyno, about 404 Crank HP.

You should be looking at 420HP+!!

You're gonna love that car.
