Boost pressure dropping off.

Hi
About a month ago when I was out for the weekend with my partner my seat leon fr got a misfire. After being recovered home and taken to the garage, it was found that a valve spring had snapped . Anyway got the car back and now it feels like it has no guts. 1st, 2nd and 3rd kind of ok but anything after that, well just feels like I'm driving miss daisy. Can anybody help narrow down my issue please. When I first got the car it was rapid as f@#k, now I'm getting impatient getting to 80 lol. All advice gratefully received
