Ok guys my car came stock obviously since I have te Y87 package, but I decided I wanted more of a punch off the line so I swaped to GM 3.73's. Now I have a speedo. correction problem. I have a Hyperech programmer and the gear option dont go up to a 3.73 gear it only goes to a 3.42. So now I'm left with adjusting the tire heighth. I'm not sure what to set it at. I know after its right that it will be of by 1 or 2 mph which is fine with me but 5 off i have a probem with. My tires are Nitto 450's 245/50/16. So if anyone knows wut to set my tire height at pease help a brotha outand let me know. Than guys
