Suburban runs like it should.

Reviewed By Robert W A (FREDERICK, MD) Reviewed for a 2011 Chevy Suburban —1/12/2015 10:07 AM

I purchased this more to disable the fuel management program and recalibrate speedo for larger tires, but decided to do the full tune. I am very pleased with the outcome! The truck doesn't lunge while downshifting (because of AFM), it shifts smooth and confidently, performance is improved, gas mileage stayed about the same as w/ AFM, and it doesn't require 93 octane. Even w/ an exhaust system and cold air intake, the tune went smoothly and never any check engine lights. Very Happy!

Big performance increase. It shifts really hard. I am not sure if I like this or not. Gas mileage increased about 5%. I was hoping for more.
