Worked just like it should have, I got all parts before I was supposed to which really helped. I will be using auto anything for things I expect to purchase in the future. Tuner works as advertised, got about 6mpg more after installing the GT platinum. Which is weird because the truck is so much more responsive and has way more power. Truck was always hard to start since installing the unit it starts first time every time. Not sure how it fixed problem but I like it!
