Overall was a good buy. I didnt know that the tuning was pre programmed until I got it installed, which took forever because the manufacture directions were wrong. I have noticed an increase in power and proformance, and I have notice my gas tank last about 3 days longer. Im dont think its the chip doing it though. The display shows me how much gas percentage wise Im using, so its making me drive smarter.
