Ive recently lifted my 2000 tahoe 2wd with 5.3L. i only used the 3" spacers on the rear and torsion keys for the front. went with some 315/75/16 wheels and tires and now i was wandering if there is a way to calibrate the speedo to the new set up. i was on the highway last night and my speedo said was doin 65mph but when i went passed a radar thing on the side of the road that tells you how fast you are going, it said i ws doing 72mph. i know thats a big difference. If anyone has any info on this procedure or the type of shop that would do this besides the dealer that would be appreciated. and i live in southern california so speeding tickets are my enemy cause highway patrol is always looking for giving out tickets.
