When using a FAST, we set the fuel pressure in the beginning, then all adjustments and done through the VE table for fueling. I like 43-45lbs with engine idling and vacumn off the regulater. You will either need to add a little fuel in the VE table where your little blue bubble travels through on the VE table or raise or lower the AE vs TPS in the fuel tables. Usually moving the line up or down will affect your fueling off idle.
