In addition to the turbo size thing the FSI also has slightly different cams (or cam timing) that shifts power a little more towards the top end.
I ran an open DP on my car for a couple days and although drag results weren't any worse the car felt a lot slower because while it accelerated the same there was SO much noise and vibration it felt like it should have been going much faster!
