Was easy to install,performance is great,burns tires first 2 gears w/4wd truck,gas mileage not so good,dropped about 3+mpg down to about 13.7mpg,seems to be running real rich as black smoke out of tailpipe like a diesel when you floorboard it.was expecting better mileage and performance.
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.
