MK1 Cabby 1.8 G60TSI Buildup

What are you all's thoughts on the TSI setup? I'm looking to adapt it to the 1.8 G60 engine, and have seen a few people who have managed to make it work. It would appear they didn't use the charger cut-off though, so they are robbing themselves of power a bit. I'm looking for more people's input, if they have any, on how to better improve this for use with my setup. See the link below. Thanks!
