Hey Guys,
New to the HPTuners world, having a great time with it so far, but I had a question. I was wondering if it were possible to program the vehicle (2002 Suburban 2500, 6.0L, 4l80E) to downshift while in Tow/Haul mode as if you were manually bringing down the PRNDL321 shifter? Would be wonderful to help with engine braking and getting the vehicle slowed down while towing. I am just not sure if this would be possible on this vehicle, does anyone know?
