Turbo "poppin" and over-boosting

My 1.8T is fine if you feather the throttle... and it pulls great.

However, if you accelerate harder (in any gear) then it just "pops" and doesn't want to boost at all.

Any ideas off the top of your head?

Cheers,

EGT sensor on its way out can do this.

Not a MAP sensor or a vacuum leak?

Sorry, didn't see the overboosting bit!

Yes, much more likely to be N75 or turbo control line. Could also be a boost leak.

No codes on VCDS?

When I had this it was a lean misfire. Check your hose to the FPR.
