Perfect Pass Problems...

So my buddy has a 2001 Super Air Nautique 210 with the stock Perfect Pass Pro. This is what it does...When you get up on plane, it beeps to set the speed, but it drops too low, then it tries to fix it by speeding up, but it goes to far, then it drops and goes to low...it never just holds the speed. How can i adjust it so it works better?

Adjust the Kdw and NN settings (pull rate and reaction). Or as my brother would say....RTFM.

I like to start with the reaction (NN) setting and then adjust the pull rate. May have to play around with it until it holds but it should stay within roughly .5mph or less of the set speed.
