I had to get the Hyper Tech speedo recalibrater due to the SCT only adjusting to 34.5" tires..Originaly when I put the 37's on which are really 36.54 vs the stock Michelon 275 65 R20 which are 34.1... I was off 5 mph at 75...actually going 80. Now at 75 Im really going 73...so I have to go back in the dash and somehow re adjust..
