I think I answered your question chitown..
so - tune the clarinet as I told you. The main factor will be you!
Don't blow straight notes trying to see if they are in tune. Play the note in a context. There is a difference!

Another tip is that as you go higher in the notes you do need to squeeze a little bit harder with your lips.
Make sure you listen !!! to what you are playing. And do the exercises of mechanism with a metronome and a tuner.!!! That will build you up!!!
