Went 12.33@110 with tune and mufflers

Added a JLT CAI and matching tune. Best time is 12.44@113

Picked up 3 mph but lost a tenth. Its in the 60 ft.

Its .12 slower.

So gears or converter and what gears or stall speed?

The 12.33 was a 75 degree day and the 12.44 was 85 all passes made without wheel spin.

What should I go with 1st?
