Review on Electronic Controller Accelerator Compatible Challenger by Brian Warmack

I have installed it in my JKU 2017 since July and it works great. I didn't get to the extreme end of the spectrum...mainly in the realm of most reviews. I left it at 2.6 for a while and don't even think about it anymore. I started a bit more aggressively at 2.8 and 2.9 but my tires are getting to the point where they suck on wet pavement so it doesn't have to be touchy. I plan to try ECO or something similar when it snows. Unfortunately it hasn't been ridden in a long time, but I think the ECO would be more ideal when hopping rocky trails.
