I've had a B7 with stage 2 Mrc and full carbon clean and although I loved it, its not the fasted. When I bought my S3 and had it running Apr stage 1 I had a little go alongside my mates stage 2 B7 and the S3 just had it, never did any lunches though, just rolling pulls. Now I'm stage 2 the B7 would get annihilated.
