You need a boost gauge and then, once you know what's going on you can look at wastegate fiddling and maps.

Get it VAG-COM read and find out if there are any faults in the car that are causing it to go into limp-home mode.

Is it in limp mode though as it revs all the way :undecided:

You have one way of finding out and that involves a cable and a laptop.

I think you can use generic units on it, as it should be an OBDII port, but my experience has been VAG-COM.
