FSI 2.0T 300HP

I recently came across the first production line turbo for the FSI 2.0T. It says that it adds around 300 HP to the base 100 so it would put you at 400 HP at the fly wheel if I am reading correctly. Here is the link, and any info about what the actual performance would be nice. If this does what it says then I am going to sell my soul and buy this upgrade.
