I have 295/35/18 in the rear and 3.73 gears. I am going back to stock, now I need a speedcal or something because Im not keeping the sct chip in. How bad will my speedo be off?
you can have it fixed at the dealer. I am not sure about the 18" wheels but theyll prob charge a hour labor to connect wds and recal the speedo. Make sure the chip is out first.
