What is the max fuel pressure I can use with DW injectors?

We recommend a system operating pressure of 40-80 psi for best performance.  Max pressure will be dependent on the specs of the manufacturer.  Bosch EV14 max pressure is 8bar or 116 psi (part numbers starting with 16, 17, or 18).  We recommend a max pressure of 7bar of 102psi on Denso injectors (part numbers starting with 21 and 22).
