I did notice a big differance over the pre loaded ones. They also need info from my ecm to make the custom tunes work better. I picked out the "bazooka" engine tune with the "race" mode for the transmission, it shifts hard and is a as fast as she will get, for when I am looking to run it all out. Then I chose the "Performance Economy" engine tune with "chill" as the trans tune, its my daily driver tune. It shifts very nice but is a little more firm than stock and will still roll out very well with my EGTs always staying below 1200. Then my last tune I use is "light towing" engine tune with "chill" trans tune. Its for when I have my camper on but it is ment for loads less than 5k. When I do heavy towing I run in stock mode or the pre loaded towing tune.
