My eco boost flex has over 12 compression ratio and just returned makes at least 420 crank HP... probably closer to 450. The car has no discernible lag that I can tell... stock it hits full torque from 1800rpm to something like 5600rpm and my retune mostly just raises peak boost... all on 93octane. The new Toyota/Subaru has direct injection as well. I know a twin turbo ford v6 isn't the same as a 2 liter boxer 4 but I believe VW gti's are pretty lag free with a decently flat torque curve. This tech would probably be more costly than a supercharger but if you are talking fi then its still something to consider.
Edit: A 2.0 inline 4 isn't a boxer 4 either but it is a least a small, four cylinder engine with a single turbo set up.

Excellent post in my view
Subaru Engineers already have stated the engine has sufficient strength to be tolerant of moderate boost - say up to 10psi
