Purchased tuner for increased MPG and shift point adjustment (but the latter was fixed with a tire size program). Running 87 tune went from a 12.4mpg avg to a 16.3mpg alongside an AIRRAID JR. & Green filter (in the factory airbox). Also had issues with it shifting into higher gears too quickly & not downshifting correctly. A quick tire height programming fixed it. (even tho I run factory 20" wheels and tires). Speedometer is now spot on as well. WELL worth the $$$ spent. Highly recommended.
