Just thought I'd share what one of the beta testers for the Flashpaq 3865 said about the tranny tuning.
I'm running the same shift schedule, and it is amazing! The great thing about the reduced TM, is not that the shifts are "neck-snapping" firm, it's the fact that the shifts are VERY fast. The truck literally keeps pulling through the shift, which is what we all want. You no longer have the "sling-shot" shift where the truck has a momentary pause before snapping into the next gear; this is most notable under WOT shifts.
