I ain't buyin it. The dealer calibrated my speedometer for the larger tires with no issues and when my 4.10's were installed, 4 wheel parts calibrated it as well. I didn't have any lights and nothing shut off. The stability control would slightly engage occasionally but that was about it. I haven't seen the little traction control light since the trutracs were installed either.
It seems they have a problem with the programmer to me. Hopefully they sort it out, I really want one of those things.
