I'm running some nicer gauges on my tester, I learned a long time ago those mini gauges suck for any form of real accuracy +/- 10% on a small face over 300psi is a large deviation.
Sounds liek the other posters reg does the same thing mine is doing - I will just let it ride for now, and if I see any issues at season start I'll look to clena and lube the LPR again and maybe break down the tester.
