Yes this was done with the 346 gears, they work guys they really do, and my car bounces off the revlimiter at 6500 rpms then the motor pulls a stupid amountof timing and it takes over a second to shift, rrt will diagnose the problem and determine if it's the tcu if not then they will fix it, if it is then they will log numerous runs on and off the bottle to see, then send all 5he results to Rudy and he could adjust the shift points for my car my car needs to shift right at 6000 rpms no higher once it goes above that if freaks out also throwing my Afr's way off, while the car isn't shifting it's staying between 11.7 and 11.9 sometimes it crosses over 12.1 through 12.3 right before it shifts. So the car I'd still say isrunning on the rich side and leaving power on the table once this problem is fixed I might do a custom stall converter and stall to 3000 rpms and launch on nitrous aswell.
