Adjusting the gear or tire ratio in the tuner only affects the speedo/odometer/ABS/transmission shift points.
Nothing for performance.
Now, changing the gear ratio in the truck physically, will change the trucks power band.
You will gain more performance in lowend of the powerband.
Any Idea of a good streetable gear? One that may better handle the factory 20" ID tires?
