I'm getting ready to put my winter wheels and tires on. Going from a 305 back to the stock 265's. Right now my speedometer is calibrated for the 305's. My prefered dealer is over 50 miles away and I'm wondering if anyone besides the dealer can re-calibrate the speedo. For instance, I've heard of people going to auto zone to get codes cleared. Is it possible that they can adjust speedo's too? Or can this only be done with the smarty and/or the DRBII at the dealer. I'd like to save some greenbacks if I can.
Thanks!
Thanks!
