    Are you checking it with a full battery and the throttle wide open? and with the other plugs in?

    That is a low number but they are all even so it will run just be down on power some. Don't know the exact number but I think stock is somewhere around 125.

    yeah im suffering with the power issue the ski will redline on the trailer but once i get it in the water it wont go over 3500rpm i dont know the FI system well enough to figure out what the problem could be.
