** Higher Pressure Settings require the use of both
Small and Large diameter springs. When using a Dual
Spring setup the resultant pressure is equal to the sum
of the individual springs.

Note: Boost pressures are only an approximation
based on intake manifold pressures equaling exhaust
manifold pressure.
