ESS T2+ Vacuum readings

hi, I have a question about vacuum readings in my new setup....
first Im just install the ESS T2+ supercharger without the FI Supercharger camshaft (248 intake/256 exhaust), and my Vacuum reading was around 15~16, now I install the Schricks Camshaft for Supercharger (248 intake/256 exhaust), and my vacuum values drop to 12.... its normal?, what are suppose to be a good vacuum values with this setup?

regards

My readings were always around -12 at idle (stock cam). But I have been chasing a vacuum leak for couple of years now so I'm really curious what other people get at idle.

The pre/post laminova numbers are very important. If I had correct information I would have found my boost leak long time ago. If your boost gauge (pre laminova) doesn't reach at least 10PSI with TS2 you have a leak.
Mine was reading 8-9 which I thought was normal based on the TS2 specs.
