Me like chipey too! FWIW, I did have a problem with it. I even got an RMA and was getting ready to return it. Problem was, my climate control display went dark and the heat was blasting me (hot days here right now) AND the service engine light came on. Fortunately, my friend Hucky (in his infinite brilliance) suggested unhooking the ground for a bit and then reconnecting. Man I was so happy to see NO warning lights, the display lit again and the A/C starting to blast. Thanks again, Huck! And YES, there is a noticeable increase in acceleration and YES the shift points are noticeably smoother (I think the sychro meshes a little longer before shifting). So all-in-all, you would be hard pressed to find a better upgrade for a couple hudred bucks, IMHO. WARNING!: Remove the chip before factory service! They will use ANY excuse to dishonor your warranty!
