hey guys, quick question:
put a set of 235's on my dually and they threw off my speedo off by 4 or 5 mph. i think the shift points on an auto are also affected by this. can DC re-program my speedo to fix this problem? i've seen boxes that wire in to do this. if DC can't fix me, where can i get one of those boxes for the best price?... thanks... . james
