I installed this very easily. The tune is noticeable and makes spirited driving more fun.

I was most impressed by how fast it tunes your vehicle and goes back to stock in a matter of 4 minutes I mainly purchased it to eliminate my DOD it works I used the 91 octane tune and removed my speed limiter I tried both firm and hard shift mode which makes a big difference but I use normal shift because there are stories about my transmissions reliability my gas mileage is crappy with or without DOD it always says avg milage is 18.9

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.
