Katana Shock settings

What's yours set at if applicable, and how much do you weigh?
I'm getting some traction loss (i think) during high speed cornering.  Rear end feels a little unstable when i hit it hard in the corners.  
Do i need to adjust compression, rebound, or both?

Mine is set on 2. I am 190lbs. Stable as can be. Tires are a big factor in stability. I run Perreli Diablo tires in sizes 110/70 F and 150/60 R. I also have a 4.5" wide rear rim.
