No. Renntech tune sucks. Not only that, but 7 speed DCT wannabe manuals suck too. Ha ha. Just kidding. Sorry. Couldn't resist. I just wanted to see BuraQ's head explode.
Seriously, BuraQ has had excellent results with the Renntech tune and I don't see any reason why it wouldn't be compatible with other N54 e9X cars. Have you checked w/ Renntech directly?
If you are looking at strictly flash tunes, you should also consider Cobb as you can flash from home, have a TON of maps for different set ups, can custom tune, flash back to stock on your own for service/warranty work, etc.
