So i have a customer with a 2017 1500 with the 6.2. All he wants is the DOD turned off, set the speed limiter up, and a little more power if possible. can anyone help me out with this one? I wanna know if i can do all this without un locking the TCM and if ill still need the 4 credits to do just the PCM? it seems as if these new trucks are getting harder to tune, i mainly just use my tool to shut off DOD on the GM and Phasres on the fords. any help would be greatly appreciated as im suppose to have it done tomorrow
