No problem at all if its a few PSI high before coming up to operating temperature. Completely normal. HOWEVER (comma) when you're just ditty bopping along in steady state flight, the XMSN Pressure should be consistently in the continuous operation range.
I suppose that some guy with an enormous brain came up with that range, so why second guess whats ok and whats not. Green is where it should be. Like I said, we had the same problem, engineers happy to leave it alone, but we pushed the issue a little and it turned out to be a rather minor procedure to adjust the pressure down a PSI or two.
For what its worth...
