425 RWHP C6 A6 with a set of AFR's
 

I finally dyno'd my friends 2007 C6 A6, before the AFR heads and cam the car dyno'd 362 rwhp, with Kook's headers and LPE ported LS6 heads. We gained over 60 rwhp by removing the LPE LS6 heads and going to a set of AFR 205 heads and the cam I call the E-test cam (224/230). We might be installing a Fast 90 and a larger cam to see what we gain.
