bi-turbo vr6!!!
now thats the way 4wrd! 
Would not work on a VR as you only have one bank and manifold.

Twin turbo setup would work, but not a proper bi-turbo setup.
And yes Dan, I agree with you there bud, QPeng is a bit expensive. I expect him to drop the price a little soon as more people are running standard ECU as its not too hard and there is lots of help/advice. Also with the 2.0 TFSI engine starting to appear now, he's going to want to push that and move the 1.8t aside.
