    The 2222 regulator only goes up to 45 psi. i have a higher HP motor that will require high fuel psi. Do you sell one that goes to 60 psi or will the 45 psi work on a 500 hp motor?

    No, unfortunately we do not have a regulator that works at a higher pressure yet. You will need to pick up an EFI regulator that goes to about 75psi. A good starting set point for 500hp will be 60psi. You may need to go as high as 65 or so as a final number.

    With that in mind, when you use the returnless system does the system automatically adjust for higher HP engines. Mine is a zz454 BBC, 440 HP at the engine.

    Yes, the PWM system actually monitors engine load and injector duty cycle and increases fuel pressure accordingly to keep the injector duty cycle around 80% at WOT.
