Do they not make one for a 98 trans am? They say they are for 99-01 But whats diffrent bewteen 98 and 99 they are both OBII. If not what is a good tuner i can buy just to set my speedo right? I would really like to get the Diablo because my car was tuned my TTP so i want one that i can just go in and set the speedometer right and not mess with any of the other settings.
