Engine type help please

[MateyGuv]

Hi,
I don't normally post cause usually I can find any answers I need by searching but can't help myself on this one. Iv got an edition 30 and fitted a revo intake which I love but do want an engine cover so bought a TTS cover for it. The Audi cover has TFSI on it which I like but my old engine cover had FSI Turbo on it. I plan to fill the hole where the Audi badge was on the cover but want to keep the engine type. So is my engine referred to as an FSI or is it a TFSI. From my searches it seems it is called both? Anyone know for sure?
Thanks for any help guys and girls

You've answered your on question, yes it's both

It's an FSI engine with a turbo, so add the "T" at either end

Perfect - so I can leave the cover as it is and it won't be wrong. As I was writing it I thought it may be a stupid question. Thank you mate
