I have an Innovate MTX and it maxes out @ 100psi on cold start. Driving around town I see around 17psi at fully warmed up at idle and 15psi if I'm really banging on it. I did 12 runs @ an AutoX practice day and as temps rose, the pressure dropped. At it's lowest, I think I saw 9-10psi @ idle, which was after 4 runs in quick sucession. I should note that the temp maxxed after 2 runs back to back and stayed there.

A good rule of thumb is about 10psi per 1000rpm, like someone else mentioned.
