Hi Everyone,
I'm considering an S4 for my daily driver.
I currently drive a fully built 2010 Camaro SS with over 850 HP at the crank. (http://www.camaro5.com/forums/showthread.php?t=92219)

I love modifying my cars and like the idea that the S4 already has a SC.

Has anyone upgraded to a smaller pulley on their supercharged S4 with a tune to make more boost? What were the results dyno sheets?

Any help would be greatly appreciated. thanks!
