Extremely happy, when I put my foot in it you can really tell the difference, I recommend this Superchip for anyone who wants to increase their horse power

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.
