Easy to install and price was best. I tuned for performance 91 octane. Accelerator is now more responsive.

This programmer is easy to use and seems to increase power and gas mileage. My estimate is 1.5-2 mpg more and I could feel and hear a difference in performance. I would recommend this to anyone trying to squeeze more mpg's out of their vehicle.
