Air Suspension Air Pressure Variance

[spydermanstever]

I have a 2015 Spyder RT Limited with the compressor controlled air ride system. Since it has been raining for the past week and I haven't been riding, I decided to stick a tire pressure gauge (one with screw on adapter) to the Schraeder valve under the seat, leave it there for the week and view it and monitor the pressure daily starting out with 50 psi setting. Here is what I got for PSI measurements - Sunday 50, Monday 49, Tuesday 47, Wednesday 46, Thursday 44, Friday 43, Saturday 41 and Sunday 40. So a loss of 10 psi over one week, in a heated garage maintaining same temp, machine never started, and never sat on. Has anyone ever checked theirs like this? I know that when driving the compressor does cycle some times, but not regularly, and I am assuming it is adjusting ride height based on road conditions, stop and go, etc. Should I be concerned?

That shock has a pretty small air capacity: you're probably just reading the amount of air lost from it, when you are playing around with your pressure gauge... nojoke

I bypassed the compressor and went to manual filling at the shrade valve. My spider was in storage all winter, 6 months and it showed no loss of air.
