Did Mitsubishi revise the turbo for the N54?

I know the topic on the turbos has been thoroughly discussed, but what is not clear is as to whether for those who got their turbos replaced ... did BMW replace the turbos with a new improved part from Mitsubishi or is it the same part number.

For 07 and 08 models, BMW stated they fixed the turbo issue by remapping the software by slightly increasing the turbo lag,which would only be noticeable under certain conditions.

Well after some more Google searching it appears that new wastegate rods were added to the turbos and post 08 models did not have their software remapped as a result. I guess this answers my own question.

Had my turbos replaced 2 weeks ago under warranty for wastegate rattle. It wasn't even that bad IMHO. I was told that they used slightly upgraded turbo parts at the time of service. I could post the part numbers if people are interested. Invoice is in the glove box now and am feeling lazy. If there's interest I'll post, but it sounds like we're settled here.

My car is a 2008 for reference.
