I'm trying to get Ram to do something about the danged TPMS on later model 2500s. I understand that the TPMS used to have a toggle, that the pressure recommendations used to be for heavy and light loads, and that up until just a couple of years ago the computer could be reprogrammed to "ding points" other than factory.Would you guys please help me compile a small list of factory inflation recommendations over the last decade or so?

2016 2500 with LT275/70R18 is 60 Front (GAWR = 5500), 80 Rear (GAWR = 6500).Actual scale weight for daily use (in my case) is 4000 Front, 3000 Rear.

Yeah, yeah, but the deed is done. Now I'm pestering Ram.

As I understand it in 2015 they implemented a new protection scheme for the ECU so far effectively locking out tuners. Diablo has their own PCM https://www.diablosport.com/news/2015-2016-ram-1500-v6-5-7l-2015-ram-25003500-6-4l/However it doesn't mention TPMS, I suspect that might be controlled by the BCU.. not sure.You should be pestering the feds that mandated TPMS..
