Yeah, it was after he dropped support for S63 so the only way to get one (new) now. I know a few of you guys are running beta ones so maybe you'll have better experience, but running a converted one (which Terry said should work) was a nightmare. Just like other cars the JB4 supports, there is nothing you can do in the JB4 that you can't do in the DME as far as performance tuning goes. Not saying our DME tuning has progressed to the level of say the 335i guys, but any gains you realize on JB4 are possible to realize on the DME only.
I was also told MHD should (hopefully) be supporting the S63 around summertime. So once that happens pricing for tuning will drop sharply as places like Velos/AA/etc. see that their business model of charging $1500 for a tune is unsustainable.
