I can attest that I've had the TPMS light come on after I reflashed the setting to 30 psi with the superchips and my tires fell below that.

Also note that auto parts store and gas station tire pressure gauges are garbage. I have two of the exact same tire pressure gauges bought at the same store at the same time and they read 5 PSI different between them. You can buy highly accurate gauges from a road racing supply house but they are like $80.

With that kind of error margin you might be close to 34 PSI or possibly even above it in reality. If you can get your hands on a second gauge it'd be worth seeing if it agrees with the first gauge you used. That or set the pressure threshold to something high like 40 PSI and then drive for a few on/off cycles and see if it comes on.

I check the pressure weekly just to maintain Even tire wear.lol

I actually sold my stock wheels and tires with the sensors and I haven't looked back..

I cant see paying $300 for a programmer when I still need a stubby and winch

just my .002

Also, it might just be some sort of placebo affect, but the JK seems to respond better even on this economy tune. I want to run a couple tanks first before switching to the 87 Octane. That's what I'm really interested in seeing. I'll report back in a few.
