1.8 t with over 270 ps. good or not?

Greetings! have no audio tt, but the engine in meim corrado i.e. it will be installed at the moment and on Saturday hopefully ready to ask, so it is the 1.8 t from ttt with 180 ps and it now has 17000 km on it. chiptuning I also have to do immediately, if already power, then right, so on approx. 220-230 ps. he now has the ko3 turbocharger in the small tt engine as much as I know…you can allegedly come by mounting the k04 loader then on approx. 260-280 ps. chip is tuned etc. do you think this is useful and is a simply too much for the relatively small 1.8 liter engine? will my everyday car be summer. so 230 will be enough for me for the first time, is only for interest, because the increase to 260-280 ps would cost only about 1300 euro… but don’t know if my car can bring this on the road without 4×4??
