I have a bmc-cda on stg2. It's in my garage atm. I swapped it for a smoothed airbox and panel filter cos i was fed up of the noise and to do some logs out of interest. i dont see much diff and i'm reasonably sure i posted logs of both but were done a couple days apart (took me longer to smooth out the box than i thought!) so not comparable in my eyes.
I might try doing logs same day but prob wont have time till next w/e.
I think i found best results were from disconecting the duct to the bmc a centimeter or two (I was worried about water intake at the time). This gave an increase in flow of 10g/s or something daft but increased the noise even more.
