Hello Patrol ppl, I have a weird problem with my 2.8td intercooled GU. I have asked many ppl what they think nobody knows whats wrong lol , so first 30-45 minutes of driving has no boost at all , and driving up to 2500 rpm its revving its guts out an cant even drive up hills , bitumen hills ! and i get overtaken by semis lol, but after that first 30-45 mins of driving the boost starts kicking in and its drives perfect , nice acceleration, revs to normal rpm etc, does anybody have any ideas?

First question is do you have a boost gauge in the car, or when you are saying boost do mean the feeling of power?

Sounds to me like the wastegate is sticking open slightly or the housing has a crack in it that is starting to seal up once everyint gets nice and hot.

I would start by pulling the wastegate line off when the engine is cold and see if the symptoms change.
