If Autotech or the like would finally get their HPFP in from Ford and start playing around with it we may actually get a HPFP solution...until then yes it seems to be the limit without running AUX. I know 4DR and myself have both contacted them, but they seem to be dragging their feet on that one. Do we know if the HPFP is the same in the F150? I wonder if the one in their engine might be beefier.
