The idle bleed screw gets its air from just above the throttle body, an area within your "pressure vessel.” Other than leakage past the rings, which at 15-psi will be nil, the only added leak source should be the throttle plate shaft and that should also be nil.
Have you removed all hoses from the intake and intercooler, plugged the orifices and pressurized? Once that part of the intake system is found leak free or damn close to it, start adding back the external goodies one at a time – you’ll find what your looking for.
