Default Vac on boost gauge really low...

Since i had the front mount cooler fitted the vac on the boost gauge reads between the 0 & 10. It used to be around the 20 mark, is there a problem or is this just because of the bigger cooler?

Thought that might be the case. Would that make the revs at idle higher? Its reving at about 3k. I found a pipe on the actuator had come off but when i refitted it it made no difference.
