    Vtech RPM varrying Help!

    Alright I'm running a bone stock 60hp 2up with the 402 tune, I was running hard across the bay yesterday and noticed I was only turning 7400 rpm all out, and wasn't pulling quite as hard of the line, I made several runs to confirm this, and indeed only 7400-7450 rpm at about 46mph, I shut the ski off, floated for about 45 seconds to a minute, started it back up and it was back to pulling hard, and running 7950-8050 rpm at 51 mph WOT. Ski has 14 hrs and only about 2 of those have been with VTech. Never had a rpm variation with the stock programming. Help!
