    Vtech Tune banging rev limiter at 8800 rpm on take off

    So top end wot I see about 8150rpm and 8350rpm in chop. I noticed when I pin it from holeshot I am hitting 8800rpm, and the cavatation I was suspecting from the skat trak prop needing repitch may actually be me hitting the limiter. What do you guys think about my observation? When I had it on trailer in sport mode I first noticed it making the same sound as my hole shot. I am running the 402 8500 rpm tune.

    I see that when I jump at WOT, I think that is what the Ecu is reading momentarily, not sure. I will however say you are not the only one.

    Slasher you talking wear ring? I don't think it is that, it does this on the trailer no water revving it up. Maybe I will take a video, my old videos out of water were all in touring mode.

    He has ss wear ring. Mine does the same thing no big deal. When out of the water or cavitating the load is removed or drastically reduced witch allows is to spin up very fast and tag the limiter. I know the 8800 you are seeing is higher that the 8500 that the limiter is set at but I think it just climbs so fast that it goes past the limiter by a few hundred rpms

    I think it is kind of annoying, it feels like cavitation. My other ski (96xp) doesn't do that on the trailer.
