I have a tfsi FR too and it has been remapped, mines sitting about 245/250ish. I can remember from researching before on taking it to stage 2 which was around the 270/280bhp mark that i was going to need, from memory, a high pressure fuel pump and the upgraded K04 turbo like you would find on the Cupra. Maybe something else too... a new downpipe perhaps...
Like you i'm not into it anywhere near as much as i was a few years back but i'm sure someone can confirm what i'm saying to be true or false. I just wouldn't want you going and getting it mapped "to the tits" and end up blowing your turbo or worse.
