Hi

I have just changes the turbocharger on my V6 CDTi. It was drinking oil. I then have a spare engine which has covered 60.000 miles where there is a turbo attached. The engine that I have in spare has a timebelt damage, so no damage on the turbo.
After 6 hour fitting the turbo the engine was spinning again. But it now feels like it´s being pulled with a rubberband attached. This only shows when I floor it.
No spannerlight at all. Starts perfect and dosen´t smoke as much as the old turbo did. It also pulls like is should beside the feeling of being pulled in a rubberband.
Even my wife looked at me and said "what´s that??" when we were both on a drive.

Does anyone know what could be the issue.
LMF?
Boost sensor?
Injectors?
anything else???

Would appreciate any answer.

Thanks lads...
