The test was for max boost. 90psi - 43.5 = 46.5

35psi of boost would've been 78.5psi where there is a giant difference between the 255hp and the 450. The 255 would do about 185 lph and the 450 would do 230ish lph.

The fact that Shawn was only on 35psi and with the obvious difference in flow between 2 255s and 1 255 w/ 1 450, shows that something is restricting the flow or the FPR diaphragm is toast.
