Maybe I am overthinking myself, but according to this chart by vortech:

http://www.vortechsuperchargers.com/pdf/manuals/superfmuim.pdf

It shows I should be using the 2.22" disc/ring combo with the 525's for around 18+ PSI of boost.

Has anyone else changed from the 2.72 disc for higher boost?

Its new to be since last year I just ran 16-17psi normally on the 2.72.

Should I keep the 2.72 in or change it for more fuel pressure?
