On my '01 automatic I had a Superchips Flashpaq programmer on it. I think it adds about the same power as the Edge EZ. I had it on the truck for 7 years (2011-2018) and was happy with it...big difference over stock. Always left it on the "heavy towing" setting. It really needed a tighter converter, but I never changed it. Pulled my 24' enclosed trailer w/ a 3500 lb car in it pretty well. I'm sure a converter would've made a huge difference.

Sold it this past fall and went Duramax.
