Got my new tunes from Justin and they kick ass! Always thought I needed lower gears but my 3:42s are fine, tuning is all I needed. Drives like a totally different truck. Now I can feel the 403hp this truck was suppose to have from the factory.

Thanks Again!

Just basic autocal. Got a modded ECM tune and two modded TCM tunes, one with torque mgmt and one without. Both kickass. No torque mgmt packs you a little more slingshot on shifts.
