The 6 psi is purely related to the size of the pulley right now, We could have gotten more psi by going a smaller pulley, also we have to remember that the 390 RWHP is equivalent to about 410 RWHP on a M/T car .

You can get more boost by going a smaller pulley but for a guy that drove 2300 miles and waiting on his car in hotel room on us to finish the work, I felt the 6 psi is playing it safe right now. there was no room to for anything to go wrong .
