Is the problem with building up enough PSI that you have a small compressor? if thats the case see if you can get somewhere that has a bigger compressor so you can pump it up quick. Use the regulator on the compressor and start it at about 30 PSI then as the system gets full bump it up to 45 or 50 then start listening....
I'm no expert by any means.... but i'd be surprised to hear that a new 480 has a problem. Anythings possible (see my story above for just the high points on my quest for boost)... but i'd think you have other signs.
If you can get the drive pressure gauge installed ... i really think that will help answer alot of questions after you finish testing for leaks.
