I disagree that compressor surge is "normal" however, at very low boost I'm sure its not as harmful, but it should not be happening. Thats the point of the BOV, different springs can be used in this particular model and I wonder if they just could not find a spring that worked well. I don't know if the throttle plates and VVEL play any role in this issue either.
Are you using the DXD organic or ceramic disk? I learned it the hard way when I called Joe after barely making it out of the hole at the strip. Clutch disk welded with the flywheel at launch. Joe says the disk can handle power, but not heat so it's not made for dragging. I have the full face ceramic. Joe didn't think it was good for daily driving, but this new disk is awesome! Engagements are smooth, and it doesn't slip. He says it handles over 700 lb-ft. O_O

I don't have pictures on hand, but the bearing has a larger flat surface so it seems to engage so much better than before. I don't have the nasty judder feeling either.

Just make sure to crack the hard line to the master to bleed bubbles first, close it up, then crack the CSC bleeder. I'd pump the pedal nearly 40 times, held down hard, crack the bleeder (feel pedal sinking further), close, lift pedal and repeat. Adjust stroke such that you have rougly 0.5" of play. Resistance should be firm and not as mushy. If you did it right, pedal feeling should be the same the next morning and after warming up.

Goodness this car is so much fun to drive now. There's no more gear notchiness either.
