While air injection may be a method to reduce lag it is not one I would use. It is far better to replace the entire exhaust sytem and turbo then tune for performance. At that point I can't see air injection doing anything but getting in the way and adding weight/complexity.
Now if the engine is stock and needs to remain that way it appears air injection would help. I'm sure the air injection system could be simplified to work specifically for lag reduction. If this is the case then the graph would indicate that it could very well be possible that some extra lag has been allowed by removing the air injection on a stock engine.
