SCT tuner
I installed the SCT tuner, using 87 octane tune. Changed tire revs for the installed 20's. Didn't mess with axle ratio, rev limit drv or Neu, Idle Speed Drv or Neu, wot sifts points. Didn't know which options were best? Any suggestions.

Will it matter if I ave 89 octane instead of 87? I will go to a full tank of 87 when this tank is done. I know going lower is a no-no, but will higher harm anything? I want better performance and MPG out of my truck. Since the 20's don't get me that 22 highway driving a steady 70-75.
