I think a valve controlled by canbus data would be the best.
Throttle position, load,
The only complain I might have with the vacuum actuated valve is when in active mode, when you just start from a standstill, the engine is under "heavy" load at low RPM which, generally with a four banger, sounds like absolute crap. Same things generally when you're cruising.
Which a canbus-driven valve, you could avoid that. But I think, everytime you could with an electronic solution over a mechanical one, you're sacrificing some reliability.
I could give these a go one of these days. They look like they work like an intake butterfly valve
