Seems to work well. It is still a little early to be able to tell. Instalation was easy. I could tell a difference between the different types of tunes. The milage that I was getting on the highway was terrific to start with and I haven't had a chance to go on a road trip since changing the tune. Around town it is so hard to tell because of all the various conditions.

2001 Suburban 5.3L which was very anemic before I bought the I3 tuner. Was skeptical with the Plain Vanilla appearance, and lack of full display, but it is not lacking in the Performance Department. I first used the Default 87 octane setting. I pull a 26 ft Warrior Toy Hauler with a Honda GL1800 Goldwing in the back, that bike adds 900+ lbs to the load. The Suburban is being asked to pull more than tongue weight rating, doing a super job and added 3+ MPG while towing.
