Get a boost leak tester and pressurize the system, I actually once had a squealing noise coming from one of my couplers on the front mount piping. I checked everything over and over but found the leak when I pressure tested it.

start at the throttle body, then move down the IC piping one section at a time. This will help pin point all of the leaks use soap and water to make the small leaks more visual. Dont forget these test are best done at 40 deg before top dead center timing so the intake valves are closed FYI.
