Review on 🚀 Enhanced Performance with Superchips Flashpaq F5 In-Cab Tuner, Compatible for 1999-2014 Jeep Wrangler by Tommy Hilmy

Works as advertised. I was able to calibrate 37" tires and 5:13 gearing in my 2008 jk. Previously on the Autobahn the engine was really struggling to maintain low speeds. With 91 octane tuning it's not a problem now, I'm not that anymore slowest car on the freeway! It also significantly improved throttle lag. I didn't really bother with that and after a few fill ups the computer says a 2mpg increase. While this greatly improves the handling of modded JKs, don't expect that it is a sports car after all we drive underperforming boxes ps the opportunity to get rid of the horrible blocking sound was worth one.
