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