I really appreciate all the suggestions folks... The booster doesn't seem to be the problem here as I disconnected the main line from the booster and it did not read any vacuum at all, so I'm thinking it's the check valve which I'll proceed to check first... I'll try and post pics too.
Dang I love this forum!
