Neither have I, it's a rare beast. I've checked out 3 firms over here that do chiptuning, and only 1 had this model in their list, that's how rare it is! Have you chipped it yet, and checked how much power/torque the other components (clutch, diff, gearbox) can handle? It could prove to be too costly in the long run.
