07 GMC Sierra 1500 SLT
Re-geared from 3.73 to 4.54. Tire height adjusted to 33" (approx dimensions 33x12 50 R20LT)
The problem: In my hypertech unit, it asks for the re-gear ratio, and tire height. When both are entered, I believe I am either doing something wrong or the math is incorrect.
Truck gets about 250 miles to the tank. My last fillup was at the 302 mark. Anyone mind offering me suggestions on how to figure the math on this out?
