Have you checked the accuracy of your TSTs?
If so do you know the altitude where you checked?
Slow responding, just got back from Texas Gulf coast. I have access to precision calibrated gauges if I wanted to be precise, but alas, I figure I am well within the safe zone with my servicing. I am at 875ft. TSTs show about 3lbs below the gauge I use so, for example, I air to gauge press of 78 on fronts for 75 on TST reading, 83 gauge for 80 on the drive axle, etc, and I don't worry about it being + or - 3 as long as the dual pairs or fronts don't have a big split.
Biggest thing I found during pre-trip servicing is that adding to the passenger inside dual caused the passenger outside pressure to increase. Scratched head and then realized that the shop that mounted the pre-assigned internal 507's last month had them switched.... hah. There is a simple relearning procedure but we were in the middle of a 3500 mile trip at the time and I didn't want to give Murphy a chance to mess with me. Home now, so will do this.
