43.5 psi is base pressure. Although you can adjust the fp with adjustable fpr to try and extract a few more hp its not going to be substantial and could create a flat spot in your rpm range.

btw with just installation of the walbro your base pressure will jump to 60 so use a fp gauge and fpr to turn the fp down to stock (43.5) where the ecu is tuned for it.
