These apply to both Volkswagen and Audi direct fuel injection engines. Believe it or not, TFSI stands for “Turbo Fuel Stratified Injection.”
Is FSI or TFSI better?
Other minor differences…the TSI has lower compression pistons (and possibly stronger internals), and the fuel system is more robust than the FSI, both of which lends itself to easier modifications if you decided you wanted to slap a bigger turbo on it someday or something.
