I guess unstable may have been a poor word choice. Question I have is why so many cons to the OEM TPMS. Is it high failures, false alarms or what? Does the OEM TPMS systems monitor high and low pressure or just low pressure? If I follow through and have TPMS added to my 3500HD will I be setting myself for issues in the future?

In regards to the aftermarket alarm limits I recall that my TST 507 manual stepped me through the actual value needed based on cold tire pressure. They had me set the high and low limits to a specific percentage of the normal pressure.
