Check actual boost pressure with a proper workshop gauge. Like you say T in a vac gauge, also connect voltmeter to soleniod and check for : Full boost, does vac dissapear to capsule with corresponding 12 v to soleniod. turbo actuator should should pull up when engine starts.Should see any turbo/boost probs with this test.
