SCT X3 Tuner...
I a bought the SCT X3 Tuner several months back. The shop tuned my truck with the street option. Whcih worked good. I just added a AFE Stage 2 intake, 4 inch exhaust and 305/65/18 BFG's. Can you change these options in order for the computer to recognize the upgrades I have made to my truck? Any advice on the best options to use for daily driving to help MPG? The only option I have found is the (Tire Revs/Mile) and tuner keeps telling me there is an error. I can't seem to get the program to the way it was before I returned it to stock. Any info is appreciated...Thanks
