when it puts air into the cat, it puts very little, the holes are TEENY. it puts most of the air into the exhaust ports

You talking about the port air system, j9fd3s? I thought that was de-energized after 20,000 miles...

Look at the (S4) FSM, page 4A-31: ECU pin 1S, port air solenoid valve, after the mileage switch is ON (over 20,000), the output to the solenoid should be less than 1.5v (or, basically, 0v)

Switching valve is exclusively for the split air (back to the cat), and the relief valve does nothing more than allow vac on the back of the overboard (air exhaust)spring so the ACV can dump air. I know this ACV fairly well, I been "playing" with it for a couple of months trying to get the 5/6 ports to work perfectly with the air pump supply I've got 'em on now...Don't know if the S5"s are different or not...

Gotta admit, don't know where the air goes before it's "switched", what you described sounds good, though. I do know now that when the relief valve/ solenoid is put "out of commision", the ACV exhausts air all the time...Thx for the clarification...
