Pretty annoyed atm. I switched from the 87 tune to the gas saving tune and it jacked up the tpms system again. It's showing up the 0 psi warning and sometimes it'll say check tpms. Has anyone been able to get rid of this without putting stock wheels with tpms on to disable it again? I'm gonna be giving Superchips a call... 
You could have a bad TPS.
Have you updated your superchips lately?
In the latest update superchips added a function to Turn OFF the TPS. You may want to check it out.
Hope that helps.

Yes I just updated it a couple days ago. I was on the phone with a Superchips tech and he asked me to update and give it a try. Didn't work... I'm gonna try it again today after work.

Resurrecting a lit bit of an old thread. Installed the 3872 on my '13 JKUR automatic today. Was a little disappointed not so see an 87 performance tune, which sent me searching the forum and I found this thread. Looks like the 87 tune is being used by others, so that's what I went with. Made no other setting changes. Was getting ~270 miles per tank, will monitor the next 3-4 tanks to see if it changes. Also won't be driving until tomorrow, so haven't noticed any performance differences yet.
And it still is as slow to setup as previously reported, but it did setup without any issues.

After 4 full tanks, I'm now getting ~295 miles per tank with the 87 tune, so that's about a 1.4-1.5 increase in MPG. No other changes made. That's not too bad I guess. Getting my 33's this weekend, curious to see what I get after that and adjusting for tire size.
