So I finally got my car back in the shop to finish Dyno testing. The only changes made was my oil and I added Z1 motor and transmission mounts.ill post up data when I have the DRF's. I'll also combine the videos of the runs. Temps were mildly warm and humid, but not terrible. So the runs...

4th gear... 331whp
5th gear: 340whp 3x in a row.

When I had 3.69's and the same wheel/tire combo, I made 342. So between environmental variables, I'll say its negligible. The 347whp result must be a combination of a 12lbs loss of wheel weight and a smaller diameter wheel and tire combo.
