Okay, I did a test today of the electric vs engine compressor.
Interestingly, although I observed a very reliable 4.5 minutes between compressor cycles on my trip home, today in the cool garage the cycle time was up close to 8 minutes. And, as I mentioned before, there were a few mornings where we didn't see it cycle for more than a half hour. This makes me suspicious that there is a big leak that is associated with some kind of thermal expansion, perhaps.
Anyway, on electric compressor today, cycle time was 7.5 minutes. The compressor came on at about 105psi and turned off at about 135.
On the engine compressor, the cycle was exactly the same length, but the pressures were about 10 or 12psi higher, like you described, Jon.
So today it seemed to lose 4psi per minute regardless of compressor.
These measurements were made at the gauge in the front compressor bay driver side. It is bigger and easier to read precisely than the "supply" on the dash. I have watched the "supply" before, though, and it moves pretty much in lockstep with the one down below, so I believe they are measuring the same thing.
