This product do what they claim it does. I just had a little issue first when trying to install it but after contacting Superchips directly they had an update that fix the issue. Truck is now running a lot better.

Superchips Flashpaq F5 Tuner Reviews


Works as expected

Reviewed By Wayne B (PEORIA, IL) Reviewed for a 2013 Jeep Wrangler —9/21/2016 6:43 PM

Intuitive interface. Easy to use. Made changes to tire size. Plan on a regear in the future. Was able to turn off TPMS. I was hoping to be able to create a increased idle setting for winching, but you must have the tuner plugged in when you want to increase engine speed. Did take a good 30 mins to flash on a new 87 octane tune. Did notice a little increase in throttle response, but not blazing.
