Have a 2013 Sierra crew cab 4x4, it ran good but with the Superchips programmer it now runs great! When I step on it the truck almost jumps. Maybe a slight boost in MPG. Highly recommend if you're looking for a performance boost.

This thing is amazing. My truck as 35 inch tires on a 6 inch lift and the thing just gets up and goes like never before. I also get like 18 mpg now!!

It really does work. Before I could see my gas move. Now I don't notice it as much. City has drastically improved. Hwy not tested yet but surely it will. Truck is slower but the performance side works too if need to switch to that setting. Can't wait to tow with it also. The fuel save setting makes shifts sooner which is obvious in saving fuel but really somehow it's not spraying as much.

It was easy to use I set it up for premium fuel car runs better and I gained about 1 mile to the gallon with mixed driving. I tried to install a jet mass air sensor but it turned on all the dash lights so I had to put the stock one back on then I saw where you can't piggyback with this programmer but I'm totally satisfied with the programmer.

When my truck was stock I was getting 18 to 20 MPG with just a K&N Filter kit. Then I put a 3in lift on it with bigger tires and lost 4 MPG. Now after I program it I'm back to 18 to 20 MPG and more snap when I need it. It was well worth it. Thanks
