What is your CFM?  If it's too stiff, you can get jitter.  Try using a
value 10x or 100x greater than what you're using now.  Stuff I've done in
my app usually uses a CFM around 0.001... 0.01 gets spongy, 0.00001 is
usually jittery.  

I have always left ERP at 1.0, but you could also try reducing that to
combat jitter.

Your callback code looks reasonable to me.
