It is the best thing since sliced bread. Took care of all shifting problems, motor makes so much more torque down low, lowered crusing rpm by 300. It is the first time I dont have buyers remorse.

Awesome Results!

Reviewed By John C (OOLOGAH, OK) Reviewed for a 2001 Chevy Suburban —12/2/2017 12:45 PM

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.
