Stage 1, I'm assuming that's k&n pancake, rc40, lcb? I would set it at the rich side just enough to pass mot, from memory I use an AAU needle which is richer anyway, assuming it's a 998cc? We could do a full respray on a mini no problems .
I know a man who can paint it. Henry at sugarbeet county customs. He's on 07510 169045. He looks like Hank Marvin on stilts by he knows what he's doing.
He's going to do the cougar over the winter if finances allow it.
