Im about ready to run this car at the drag strip. I was wondering what you M62 guys do for shift points. I understand the roots blowers lose efficiency at the higher RPM's, so, are you still running the engine upto redline? or do you find more TQ if you go ahead and shift sooner?

I ran out of tq very early on, on my dyno sheet (max tq was about 3grand) but horsepower was a linear curve all the way to redline 7350 and might have kept climbing but the motor is completely stock and revving higher isnt too oem valvetrain friendly.
6450 is redline for me right now with the gm tune
