The Superchips Traildash 2 is pretty cool! I opted for the computer swap, which was fairly easy. Once I uploaded the stock config, they will send your computer, unlocked you send your stock one back. After receiving that you have the ability to tune your Jeep computer. It was fairly straightforward when switching tunes is easy, and I love having the extra gauges on the dash.
The only issue with re-tuning after a computer update at Dealer, I had returned to stock and still had to contact tech support for help with uploading new stock files and receiving new files. Additionally, I recommend installing and running this before installing an SPoD.
I consider this a MUST BUY!
