Simple to update on the laptop. Worked as expected in the Excursion. Running sport 87 with custom parameter of 33” tires. Downloaded stock program and uploaded new tune without issue following screen prompts.

Awesome programmer, able to program for my tires and gears, adjust shift and get more out of my banks intake and flow master exhaust. Truck runs so much better just on the 87 sport tune.
