Mine are set at 6400rpm. The motor peaks at 6k. When the shift points were changed for the nitrous to 6200rpm the car lost 2 tenths on motor with the same weather and track conditions. I'll have my second computer set up for NA and leave this one alone for the nitrous.
For the guys talking about pushing through the converter, you need to do a little research. There's a big difference between pushing through a converter (to much HP for a converter) and a converter that is to big for an application, which his is not.

I made it back to the track with the shift points bumped up to 6400. The first pass it ran a 11.49 at 118 and the second was a 11.45 at 118.8. I think the car still has a little more in it if I can get an actual dyno tune done on it.
I think now its time for a nitrous kit to go on to try and blow this stock bottom end up!

With a 6400 rpm did it still shift into 4th?
