Thanks for all the help. If I figure it out I'll post how.

I know this an old post, just purchased the superchips 3874 F5, did the update then plug it in the Jeep and says no application for this vehicle.

Has anyone had any success with the tunes?

I tried a few things but never got it to work on my 2005, my interactions with their support team were good but went no where. I ended up picking up a used 3875 from Amazon and have used that without issue, this was all before I discovered I also have a Unichip in there intercepting a few things. :S

I've got a 3875 in the mail coming over. What tune are you running? Did you have a play around with the cooling fan function?

I'm running the most basic setup just because I've got a Unichip in there playing with timing/mixtures already. The transmission/throttle response tuning of the Superchips is the real thing that I notice rather than any difference between the tunes themselves.
