SuperCharger to HEMI Transition?

[JeepLab]

Hey bud! moved your post, I thought it was a good thing others might want to read on its own. Here's my question,

"Hit the rev limiter twice this a.m. trying to let the auto trans to upshift on its own. It's amazing, I'll be screaming right along and then whamo!, the RPMs drop and moms in minivans are passing me going uphill on Interstate 287 North (for the Jersey guys)."

(I was 287 north today)

When you say you hit the rev limiter, your saying that you floor it, the SC sings, and the Jeep is a rocket....But it dosent shift? And you lose the speed you built?

That's exactly what happens. Say I'm in 2nd gear with the pedal all the way to the floor. The truck doesn't shift, RPMs go to 6,500 (perhaps higher - it's hard to tell) and after several seconds the computer or something else takes over and just cuts the power off. RPMs drop fast even thought my foot hasn't moved. I go from being pushed back in my seat to being flung toward the windshield. I assume it's the rev limiter or some other safety device taking over.

Sorry, I meant let the transmission upshift.
