How reliable is the TPMS on my 2013 Suburban

my new hand-held pressure gauge is 10 lbs lower than the TPMS in the vehicle??
Depends on the accuracy of the gauge and the vehicle. Here is link with others having problems, but most are within 1-5 psi......http://gm-volt.com/forum/archive/index.php/t-16713.html
