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.

Un-sure what kinda #'s mine will make on 12/9,,,but gonna roll with what's on the Z.
Wheel's & tires are a bit heavier than last tuning; but it's what i'm running & gonna hit the dragstrip with same set-up.
I'll post up when i get result's...Most importantly want the AFR/Timing correct on Z for optimal power for the few mod's i have.
Then we're going down in the 12's w/345's on 12's & 285's up front on 10's.....Wheel/tire setup will change for the dragstrip for sure-as i know these will stunt me back somewhat.
