2G auto rev range

[TSiBOLO]

I can't seem to find much information about auto DSM's and how high they can rev. My car shifts at I believe 6600 at WOT and I was curious if this can be raised safely with the valvetrain to support it. To my understanding a shift box is the easiest way to achieve my desired 8K range but is it possible on stock trans and TCU?

The shift box is the best mod for an auto. Trans should be fine if you keep your power levels under 400 hp.

FYI Also never shift into first above 15 mph good luck
