Wow, I wouldn't touch that with a barge pole. Will the gearbox on these even get to 200mph before hitting the limiter, or just exploding? I can't imagine getting to those speeds will do it any favours at all.
It's only the 4.2 V8, the RS6's twin turbo 4.2 V8 would have trouble getting to 200. Remap removing the limiter may see it get to 165. And that wrap is both pointless and st. I bet there is no V5 with it.
