Thanks for the info...what differences are there between the Performance and Tow tune? I would guess Torque would be the answer, which would equal better burn outs?
I just boughyt the 3865 the other day. I gained 4 miles in the gas saver mode so far. That is city driving. The shift adjustment feature alone is worth it. Not the 3865 had the best price.
