If you want to save a little $$, and don't need the full programmer. Why not look into the FlashCal by Superchips? It will allow you to adjust for gearing and tire size so your speedometers and odometer will read correctly. Also, it will adjust things like your TPMS, daytime running lights, and a ton more.
Shoot me a PM and I can hook you up with out exclusive JKO discount code!
