2019 gp1800r not boosting at 100 hrs need advice

Friday just putting in, motoring out of no wake zone, finally hit the gas, nothing there no boost, very slow, not in L-MODE. only 6500rpm and about 62mph. Usually 7800rpm - 8000rpm and 80++. i think it may be supercharger clutch but i dont know for sure. nearest dealer 120miles away. Recently did 50hr service and new plugs.

Make sure the hoses aren’t loose, as they can disconnect, especially after a service if they weren’t tightened all the way. After that, may be clutch.
