I would put a 63n jet in there and leave the fuel jet and fuel pressure the same, but it depends on what kinda shot your motor can handle, are you looking for the "beat Jamie" tune???Sent from my iPhone using SoCal Jet Boats
How much timing are you taking out on that tune up. Those Jets sound like a 100-125hp?

Might want to consider pulling a little bit more timing.Sent from my iPhone using SoCal Jet Boats mobile app
James for a 125 shot does a 6 jet spread with 6.5 flow fuel pressure still gonna be rich ? 5 degrees retard ? Sent from my iPhone using SoCal Jet Boats mobile app
