Reviews for Superchips 3876 Flashpaq F5 Programmer for 15-18 Jeep Wrangler JK

Purchased in June of 2018 for my 2016 JK. Adjusting for tire size, and throttle position is easy and works well. Noticed a definite increase in power with the performance/towing tunes. As a bonus, the 91 octane performance tune delivered almost a 2 mpg increase for everyday on the road driving.

works good have not had a bad experience

Works great for the things we are able to do without unlocking PCM. Will be unlocking PCM soon and can't wait for the better performance.

Useless product in that I have tried all settings and can identify no improvement in my Jeeps economy or performance depending on the settings. Would not recommend spending this kind of money for this device.

I honestly wish I could rate it lower. The stock PCM is bypassed by some cleverly placed sautered wire, if or when that comes disconnected your apt to fry your whole electrical system. In my case, costing me a couple thousand dollars to rewire and replace. Best part of it was, not only did SuperChips tell me it’s not their problem that my 2017 JKU was trashed, they refused to send me a PCM to replace my original until the owner of the shop I had brought my Jeep to told them he would no longer sell or service their products. Even then the replacement they sent didn’t work, as in my Jeep would not start with it installed. I had to spend another thousand dollars to buy a OEM replacement and return the Jeep back to stock. Awful product and even worse company.
