Default Peak power shift points.

If this was your peak horsepower, what RPM would y’all shift this engine at? 6700? 6800? 6900?

Peaks at 6700. 200rpm over was always the recomendation. Signatures see to be a thing of the past now so do you have torquehead, coil packs per cylinder, 411 pcm; basically how come to 7k can you get? Optis run out at 7k.

I'd take it to the track and play around with different shift points.

Yes my signature is old lol. I’m running a 411 pcm and a different engine from the signature.
