Moto Tassinari Air4orce

Has anyone tried one on a 10-12 YZ450? I have tried a few different mods trying to gain more topend. I don't care how you adjust with your programmer you cant make it rev like a carb model (09 and back). I currently am running a Dr. D full system and removed my cam sprockets and changed them 3 degrees for more topend. This helped but still isn't what I'm looking for.

I've yet to see it available for the bike, it always says that it's out of stock which to me means it hasn't been released. I'm not sure on the 10/11 but on previous years the Drd focused more on the low/mid not so much the top.
