I changed my gears from 3.42 to a 4.10 with 295/50/16-27.7 tall tires. My rpms on 1/2 is 6350 and 2/3 is 6300 and 3/4 is 5800 in tow haul. In normal it is 6000 in 1/2 and 2/3 and 5800 at 3/4. I used a speed calculater that blackgmc posted on here but it still don't shift right. I adjusted the rpm and shift speed. Am I missing something. Its still shifting crazy. Im using hptuners.

I also went from a 3000 stall to a 4000. Do I make any adjustments for that or is it about the same?

The looser the verter, the lower the mph will haveto be. Set the rpm where you want it. Then drop the wot mph by 1-2 mph at a time. Also make sure the part throttle table at 100% throttle match. Make sure wot and part throtle downshift tables are lower than the upshift.

Do I need to adjust the tps/rpm/speed tables??

Yes. I don't have my pc w me, but in efilive there are tables for part throttle based off tps, and wot vs mph and wot vs rpm.

I would start with zeroing out the WOT mph and just set your RPM and relog to see what its shifting at mph wise,then adjust from there..
