What other mods will need to be done with the installation of 4.10 gears? Will I need to get a flash tuner, recalibrate the speedo? How will this mod affect my top end? Just trying to make the most with the little horsepower I've got. Already have Flowmasters, and K&N on my 02 GT AOD. Not lookin to go to the strip, but I just want to be able to smoke the Camaros, GTOs, etc. when they get cocky on the street. :sterb:
