I did a timing belt change a week ago and everything seemed fine until I lost a lot of power in high rpm’s and I can barely hear any turbo whistle. I don’t have any engine related codes and I have tried to check if the vacuum lines going to the n75 valve and I can only see one that is a little more taken off but not all the way off. Does anyone know if I messed up the timing belt or did something get disconnected?

Seems like you should have a low boost code. Definitely check over every thing you moved and or disturbed.
And buy a VCDS cable. You pretty much have to have one to work on a VW.
