Supercharger slipping? Or bad spark plugs?
A little background besides the mods listed in my sig.. Ski has 333 hours, supercharger was rebuilt at end of season last year with new clutch system with the titanium washers.. 30 hours ago.. New spark plugs at beginning of this season
I have noticed the last few times out that only at WOT every once in a while (happened only 2 times today running through a full tank of gas) the ski feels like it misses just for a split second, I don't even have time to look down at my RPMs it happens so fast, or feels like you hit a wake and kind of loses power for a literal split second and immediately returns to normal operation at 8000-8100 RPMs, I'm not sure if it is even dropping when it happens because it happens so fast, just a slight hiccup
I have the mods in my sig and am only hitting 70 on the gps.. My oil level is a tad high as it towards the upper mark when cool and climbs above when at operating temperature
I do fog the motor with some fogging oil after every use.. Is my charger slipping and time for a rebuild already? Can I lose the new metal clutch washers?? Or could this be the plugs as the motor has fogging oil in it pretty often? Thank you in advance for the help!

Sounds like the fogging oil is causing it or you have a coil pack going bad.
If your charger is going then the rpms will not be that high.
It would drop to around 6k then surge up and down..
Why are u fogging so much??

Salt use, sometimes the motor will then sit for a week to a few weeks at a time, I don't fog it like winterization time, just a little to help keep things fresh

Have you taken out your spark plugs....
Also what oil do you use for fogging?

I have not taken out the plugs since they were put in earlier this season.. I use the fogging oil from any West Marine, I believe CRC brand
I wouldn't even know how to begin to reset tps on it and check percentages
Can we rule out that this is the charger slipping and may just be plugs?

You need to burn off the fogging oil and put fresh plugs in it or your always gonna have fouled plugs.

I would try to do a pull and check the plugs. Could be a I/C issue with letting water into Intake, Could also be bad coils, or simply plugs.
Start small and work your way up!

Shouldn't be a water leak in ic as the oil is always fresh looking with no signs of water coming in, I think I may start with changing the plugs..
So shouldnt and doesn't sound like a supercharger problem?
Any other suggestions?
