    Well I feel alittle better about the RPM but I doubt your still making power above 7,000rpm. I have a 251/259 with over .660 lift and with a single plane and it only makes power to 7,000-7100rpm. 7500rpm is still alot of rpm for LS2 rods, I wouldnt turn the motor that high if it were mine.

    In your log I see that there is no rpm drop on 1->2 and 2->3, and on 2->3 I see the rpm go up... this indicates internal slipping.

    This might be dumb, but what if it thinks it's in performance mode? The performance mode shift points are sky high. I always copy over the shift points to the performance, hot and cruise colums....

    Guess it can't hurt to double check. Thanks, Lee. Feel free to drive 25 miles north to Layton and come for a ride with me to see what you think, lol. I appreciate the thought... I'll make sure my performance, & hot numbers match the normal ones. Thanks again to everybody for their input. I will post back again later tonight with another update.
