Has anyone tried there new set up on an m8 yet? How do they work? It would be cool if they really did benefit a turbo set up. Maybe a faster spool up time?(not that mine isn't already wicked fast haha =) )

I put a set on my 2009 turbo M8 this year, didn't really notice a lot of difference in them but liked the idea of getting rid of the servo motor and the cables.

Running them on my Turbo M1000 and a naturally aspirated M800. Bigger difference on the M1000 than the M8. Definitely snappier on the bottom end. Also you have the ability to control the speed of the opening via springs and tension which is nice. I like 'em.
