Start at 60 and tune it. No way we can tell you the exact base pressure because gauges differ and there a bunch of other things that will effect your AFR.

Dean, you will need to put a n air fuel ratio meter on the ski and adjust the pressure so the air fuel ratio is correct.
For you're info, I'm pulling my fuel pressure reg off and running the factory regulator as suggested by Danny.... have you thought of doing the same? (added advantage is you'll get some extra $$ for your reg as well).

If you are running an aftermarket ECU your injectors probably arent big enough.

Every ECU is different!! Only way to be sure is by using a wideband.
Just guessing is going to bite you in the ass!!
