The performance tune woke up the truck! The fuel saver tune was disappointing as I did not see any real increase in mileage over the two weeks I had it set up. But whatever! I didn't buy a 5.3 nor this tuner to drive like a grandpa. I have it set all the way up and I love driving my truck. It's not over the top so you don't have to worry about blowing your engine up with it unless you're really trying or have done a bunch of other unsafe "upgrades" on your own. Prepare to do some burnouts!
