Do have hi-flows.

For an A6 that seems like a decent number. I would expect you could do a couple little things like and under drive pulley and maybe ported intake to squeeze out a little more power.

Just add a cam and you'll be over 400.

360 seems like G8 GT numbers with intake, headers, exhaust and tune. I was thinking the extra .2L would help a little more. Could be a very safe tune.
