2008 speedster 200 430 port engine issue

At the lake with my family for a week first day out port engine seems to be laggy does not quick to take throttle. Cold it'll go all the way to 8000 RPMs, after about 10 minutes she won't go past 7000. Stuck my hand in the intake side of supercharger it moves the same as the starboard motor. You can move it a little bit with some force but it seems very similar to the other side with it put back together started put my hand on the intake discharge gave it gas and it definitely pushed resistance against me. So it's building boost. I have no check engine lights on superchargers were built by PWC MUSCLE 25hrs ago. Impellers all look good I run stainless steel wear rings and they don't seem to be damaged. Oil levels are good. Any ideas? This sucks!

injectors, plugs, fuel pump/filter
check air filter/clean, check/clean throttle body (dirt/oil build up).
impeller/pump problem, muffler/exhaust blockage

K&ns air filters are new and still looks clean impeller and pump are all debris free. Exhaust sounds same. Any good recommended intake throttle body cleaner, seafoam or gum out?

remove hose and check throttle body for build up.
