R32 std boost on Australian delivered car
page EN-23 in workshop manual
"remove the intake manifold canister hose, place a cap on the hose, Connect test hose to intake manifold and attach pressure gauge.
"when engine operation check is performed check the pressure does not rise above 0.8 to 0.9 kg/cm^2 (11-13psi)"
In practice mine runs 8 psi with stock exhaust and 10.5 with a cat back
Hope this is of some help
