hi
i have a 1998 automatic transmission trans am
and i cant figure out how to calibrate input in hp tuner tires and gear ratio.
i don't see a box for the input?
my car have 305/35/18 tire, and 4.11 gear, i know i have to divide 26.4 for 4.11 and get the magic # but don't know how to do it in 1998 cars.
any help i will appreciate. thanks
