Have you used the fixed duty cycle to create a table so you know what duty cycles create what level of boost?

The Pressure vs Duty Cycle table contains a lookup of pressure valves which correspond to a solenoid duty cycle. The values for this table must be set by using a fixed duty cycle (see Control Method) and noting the resulting manifold pressure. Note that different ambient conditions will result in slightly different boost pressures for the same duty cycle.
