All, So, HPT was used to tune my truck, TC was taken out. The dash light has always indicated that traction control is off. I have the tuner's tune, and the stock tune on my laptop... took the torque management things from stock, overwrote to tuner's tune, save, HPTed to truck. Dash Light reports TC disabled, TC reports as ON in scanner, and the factory disable/enable proceedures followed and did not work. The tuner wants to see the truck (for a minor cost), but I am wondering if there might be a physical modification that is in the way. Has anyone heard of hotwiring the TC button? This would be similar to hacking the Trans wires to hold in gear for 1-2... Mike S.
