The Superchips Flashpaq is one of the most popular tuners on the market for Jeep Wranglers. It's a simple plug-and-play device that can add up to 30 horsepower and 30 ft-lbs of torque to your Jeep's 3.6L V6 engine. That's a pretty significant increase, and it's why the Flashpaq is so popular among Jeep enthusiasts.
