need pitch?

[DANNYA09]

just went out today after adding a couple of goodies to my 06 rxp. let me explain the scenario. my ski ran 69.7 all day with the reverse bucket mod, filled rideplate holes, and opas block offs. i installed a riva intake, 14/19r solas prop and intake grate.(the prop was pitched by PPG for these mods) after this my ski ran 68.3 in the same weather conditions but i did feel it pull better on bottom end. this week i installed RR supercharger impeller along with 42# injectors. i went out today and ran 70.1 without touching the prop. the ski feels like it rips. is this a decent mph with these mods or do i need a repitch to get the most out of them. this week i will also add a RR thru hull exhaust (hopefully Jerry shipped it already) do you think this will also help mph or will i get the most after repitching the prop? any advice and info you guys can provide will be very helpfull. thanks
