I recently changed my gears to 4.56 and now I'm wondering what is a better way to go with a tune. The hypertech speedometer calibrator costs $199 and will compensate for my 38s and 4.56 gears. Is it worth buying the diablo tuner and hemifever tune for $489 to compensate for Vararam and an 87mm throttle body? Thanks for any input.
