OEM '06 cams in an '09. A little more snap out of the hole, but not a huge difference. I haven't noticed any loss or gain in the top end as I never get to the end of that road any way. Sorry, I don't know the cam specs.

Looking for an '06 CDI to compliment the cams. The people on Ebay apparently think they're made of gold now, I guess I missed my window of opportunity for a cheap used one.
