I recommend using the Superchips Flashpaq F5 Performance Tuner # SU2845 which will provide you with an additional up to 18 HP and up to 17 lbs/ft torque when run on the performance tune. This unit plugs in the OBD-II port on your vehicle and comes with a high resolution color LCD screen that is easy to read. I've linked a brief video on this Superchips tuner for you to have a look at, as well. This tuner is going to provide you with the biggest potential increase in HP at a good price point.
