Good product by Diablo Sport
I bought this to see if it would slow or stop oil consumption. I have 1000 miles on after install with a fresh oil change. Still shows spot on full whereas normally would be 1 quart low. Added bonus is it feels like I am driving a totally different vehicle not having it alternate between 4 and 8 cylinders constantly.
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.
