Review on Enhance Performance: Superchips Flashcal F5 In-Cab Tuner for 2007-2018 Jeep JK Wrangler - Boost Your Gasoline Power! by Don Merritt

The first unit I received had errors. Gave it back to Revane. The replacement arrived within a few days of beginning the process. The replacement works as advertised. Set tire size. Set TPMS to 25. I don't know what the lowest or highest settings are, but they will be at least up to 20 and TPMS can be turned off entirely. I haven't experimented with data logging (which happens while driving). It's a little pricey for what it does, but it's not cheap to get the dealer to change the settings either, and it can be used as many times as you like for the initial cost. It can also be updated and updated online. Diagnosing and replacing missing files on a failed device can be done online and the update application should be able to do this without requiring a Superchips technician to have online access via a personal computer. I didn't deduct a star for that, but Superchips really needs to step up their game. Since I was not able to put myself, the tuner and the computer in one place and make calls during working hours, I simply sent the device back.
