Need help on New Turbo not performing

Hi Guys
I recently replaced by 320d (2003) E46 turbo. Now the turbo only start performing at about 3rpm and feels like only about 60%. It also has a hissing sound when it gets up there.
I was informed that it is the wastegate valve not opening.Can this be the problem. If so what must i do. Replace it, clean it, or just need some setting (if possible?)
I was said that the wastegate works on a vacuum system driven by the engine. Or so to say the presure from the oil/ oil pump. Can it be that the oil pump is not performing. How do i test this. Manuel presure test, or can it be tested on the PC?
Hope i can get some info from the forum.
Thanks

The wastegate issue was my first thought. Also check the high pressure fuel pump I'd say...

Talking

Thanks witeshark

How does the High presure fuel pump effect Turbo lagging. or do i need to read a system manual to explain this?? Always looking for the easy explanation to the un-educated.

I would look through a good manual. The turbo diesel system is great but needs to be watched
