FSI = Fuel Stratified Injection.

Have a look at this: http://www.volkspage.net/technik/ssp/ssp/SSP_337.pdf

It states: "The new FSI engines from Volkswagen do without stratified injection and place greater emphasis on output and torque. Until now, FSI direct injection was always associated with stratification. On the turbocharged engine, the abbreviation FSI remains but there is no stratified charge. Doing without fuel stratification and NOx sensors represents a loss on one part, but also promises the finest driving enjoyment with high output and a torquey engine and great pulling power and economy."

This is for the 2.0 FSI (non turbocharged) engine: http://www.volkspage.net/technik/ssp/ssp/SSP_322.pdf

It states "Thanks to FSI technology (Fuel Stratified Injection), the 2.0l petrol engine has taken on a new dimension. FSI engines are more economic, cleaner and more responsive than multi-point
injection engines. They also meet today’s requirements in terms of low consumption, environmental issues and increased driving fun."
