TPMS sensor alarms above 80 psi

[bimmerland]

I have a 2500 that is capable of pulling a lot of weight. I run 275/75/16 E rated tires.pulling a huge and heavy trailer. They need to be pressurised to 80 psi in order to have a safe ride. If i run less the sidewalls flex leading to an unsafe condition. In normal conditions I run them at 55 psi and no issues. The tpms sensor system start throwing off all codes and my dash lights up like a christmas tree. They are little bigger so my speedo is also thrown off. Is there a programmer out there that would allow me to modify my settings to accomodate my needs as well as eliminating the rpm limiter and the speedo limiter. I work for myself doing power washing on large jobs so I carry a lot of heavy equipment. One important option is that I can store these setting restore to factory settings if need be and then put my customized back in. Any suggestions greatly appreciate. Thanks
