Suburban runs like it should.

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!
Great power booster!

DI ordered the Hypertech programmer for my 2013 Chevy Suburban 5.3 liter V8,wanted some extra pep for passing, and to give engine litte boost of extra power.Wow what a huge difference it has made,so much better than the granny factory settings.I mean it would get up and go before,but you really had to stomp on it pretty good,i was not satisfied with that though.Now runs like a V8 should run,much more responsive to throttle,rpms much better....i selected all the maximum settings in all modes.

Bought this to disable the AFM on a 2007 suburban, easy to use even if you are not too technical. Worked great, installed the 87 octane tune and modified to disable DOD (AFM). Also firmed up trans shifts and took the top speed limiter off. If you are lookinjg to disable your AFM this does it easily!
