Since we have sequential Turbos on our cars...doesn't that imply sequential BOVs?

Wrong! The N54 is a
Parallel twin-turbo, not sequential. Both turbos spin at the same time and make the same boost. I'm not quite sure why the stock set up has dual diverter valves, but a single aftermarket blow off valve works as good as a stock dual set up, and is able to hold higher boost pressure than the stock DV's.
