my supercharger is suppose to be pushing 12 pounds of boost and ive only been able to get it to 7 or 8 is there anyway you can turn up the boost like on turbo chargers or no?

A lot of how much boost your car sees is based on where you live...what's sea level are you at?

You can increase the boost through a tune but as bruceg said there are a lot of factors as to how much boost you make.

Your elevation must be pretty high for only 7 or 8 lbs of boost. I was at 1500ft making about 10 or 11 when it was stock. May be a vacuum leak somewhere or your ECU needs to be reflashed

Because of the different factors like lack of push. I think you should boost it up in a turbo chargers so that it will create additional energy. :D

I don't believe elevation should have an effect on boost psi. I live in Salt Lake 4500ft and I still run 12psi boost stock. The elevation will affect power output because of a lack of oxygen (ie oxygen being the thing that supports combustion) in the air. The supercharger will take in a volume and compress it regardless of what elevation it is run at. Things like temperature and humidity have so much more a drastic affect on air density that elevation alone would not be a factor. The key point here.....lack of power at high elevation due to oxygen content...not air density/boost ability. This is at least what I recall...4 years of schooling about things like this.
