option code for 3.73's?
did gm ever offer 3.73's factory in an fbod? I was wondering because when i go to recalibrate the computer for the lower gears, (for speedo readings and odo readings), what would i select in my hypertech tuner for gears. right now its set for gu42 i believe since i have 3.42's
