Are you trying to suggest that tow/haul mode does pretty much the same thing as a tuner? Changing shift points is only one small thing that the tuner does....
But no using tow/haul is not the same thing at all. The shift points still won't be higher at full throttle than what they are set at stock. Tow/haul does hold the gears longer under normal driving to keep the truck up in the power a bit more. That doesn't change the WOT shift points.
