Atmo BOV's cause so many more problems than they are worth on an AFM equipped car.
You can fiddle with the atmo BOV, get a retune to make it work (If you have an aftermarket ECU, otherwise factor in money to buy that) then it still wont run quite as nice as a PB BOV, then get a fine for having a venting BOV
alternatively, use stock BOV, buy aftermarket PB BOV, don't need retune, drives as stock
If your buying an ATMO BOV for the sound then you can still get that from an aftermarket plumback.
This is why I say they are not worth the trouble. You are right, they can work. But why would you bother?
