Every Jeep should have this...
OK, got the PedalChip-X in today. About 4 days shipping... It's a German company. About 15 minutes to install. Not too bad, plug on accelerator not easy to get at. Works Amazing! Valet & Eco mode is crawling response. Original is factory. City boost a little. Sport is aggressive. Race is very quick response and Track Launches immediately. In comparison: Valet and Eco about 1/3 - 1/2 of floored factory power. Original Floored response. City about 1/2 pressed = Floored Factory. Sport 1/3 = Floored Factory. Race about 1/6 =f Floored Factory. Track as soon as you hit the pedal it launches. Very impressed for the $169 price! I really don't think I need a tune now, the lag was 90% of the problem. Every Jeep should have this... 6 settings is more than enough!

Worth it
5 min install on 2017 JKU Rubi in the rain. Just follow your pedal up back behind the black plastic housing for the plug. Led the head unit up through the steering column from behind to hide the cords then zip tied below. Took for 20 minute test drive and works pretty well. Fairly noticeable difference to each mode. Easily spinning tires with manual tranny in sport modes. Seems like a great value when compared to competitors.

Great value pedal control
Based of the 1 review I bit the bullet and purchased this pedal booster, so far extremely happy. Just like the review previous to me , I have used a sprint booster with more adjustments but realistically the ones on this device work perfectly fine.
I use the 3 setting , the first red light first one is green light eco mode second light is green as well but is basically oem or slightly better than oem mode, similar to stock. 3rd light is red and this is the first setting in there sport mode just enough responsiveness for daily driving, my car picks up speed much quicker and seems to pull better in areas where rpm torque seemed lower before the booster. the lights after the 3rd just keep getting fater and faster pick up. i deemed that the 4th light is more than enough for me and feels like the car picks up very fast and shifts faster too.
I tried the other modes but they are to much for the street driving ,maybe better for track applications. so far very happy with performance, and installation was super easy took me 20 minutes only because one of the clips was giving me issues to get off. patiently pried each side and it released.

It really works!! I can feel the difference for sure!

Alles gut.
