Hey y'all.

I have '17 Ram 1500 with a Superchips Flashcal to adjust my speedo and TPMS threshold. I'm on 35x12.5x17's. For the last month or so everything has been fine, my TPMS threshold has been set to 30PSI and I run my tires at 38F/35R. However, I keep getting a warning light to "inflate my tires above 30PSI" when they are all above that value already. I tried disabling the TPMS system with the Flashcal and it made no difference. Warning light is still there.

Am I missing any tricks/tips here? Will I need to inflate my tires back above 40PSI and then disable the system?
