I'm running DCT to so hopefully it will get me close to 5,5psi

A centrifugal type supercharger does not provide absolute boost like a turbocharger, it provides relative boost due to the fact that the speed of the compressor is directly related to the engines rpm. So at 5000 feet your stock car has 2.5 psi "boost pressure" compared to sea level ( 0 psi ). To get out 5.5 psi @ 5000 feet your SC kit needs to make 8 psi boost at sea level. How do you manage those 8 psi once you really leave your altitude ?
