If you have the boost fuel pressure fully adjusted on the WUR and cannot get below 12.5:1 AFR it is time to modify the fuel distributor. This is assuming the fuel distributor is still stock and using the Lambda system. Once the distributor is modified you will need to re-adjust the WUR.
The RPM switch only delays the boost signal to the WUR, it does not help with fuel flow at the top end. We handle fuel distributor modifications and I believe I have a modified -145 aluminum fuel distributor in stock if interested.
