I do believe my first 20v had the 7a cams in it but never had paperwork to verify it. My current 20v has less mileage but the same IA stage III+ software and stock exhaust and K24.
7a Cams have a different sound, lovely low growl from idle and you can definitely pick up the turbo whine from the driver's seat. Seemed to have better 1500 to 3000 rpm response. I never got more than 22 mpg also. Other variable was the waste gate had been drilled so you could tighten on the spring.
I just had a rs2 manifold installed and hoped some holes in the air box would recreate the induction noise, but no such luck. I may try some cams at a later date, the boy has some in his coupe q.
