they've taken the v8 out and put in a supercharged v6 and it's even faster, by talking to the guys it seem that developement of more ideas will keep this package in semi production for a while, the original package worked well but as with everything that is "out of the box" so to speak, there is always another idea, i don't think they are ironing out bugs they're just trying out new idea's.
i think it's a lovely package but with everything new, people will be slow to see it's true beauty, good luck to mark and co for committing to such a unique venture
