what is your stage 2 dyno like. i honestly do not expect any mechanical issue from the car. theres no codes. no symptoms of an issue. no weird noises.

I have not been on a dyno with the M6. I started with the JB4, then Mission stage 1, then stage 2 and noticed an increase in power each time it was tuned. My Saleen Extreme, after rebuilding the engine and upgrading the supercharger put down 610whp on a conservative 91oct tune and was able to put the power down to the ground on 315/35/20 drag radials. On my stage 2 M6 I can tell the car is faster than the Saleen which was 800lbs lighter and I can lose traction in 1st through 2nd on the same 315/30/20 drag radials that are on my M6 currently. It's putting down well over 600whp, if a 4,200lb car cannot keep traction on 20" 315 width drag radials you know it's making power.
