does it feel slower? i would imagine if it was genuinely boosting at 15psi and now at 5 you would feel a massive difference.

You are driving it and not revving it in neutral arn`t you as that wont show boost as there is no load on the engine

if you keep the foot down flat will it slowly get more boost after a few times?

If I take the pipe off the actuator and block the pipe up it hit 18 psi . So I think the actuator is no good.
