Good Diesel Tuner . . Southern Western Australia

I'm quite a distance from Perth, and I don't know when I will get up there next. (someone did mention a place in Perth, but I can't seem to find it now. Drop Perth in as well, just incase I need to get it done there)

I'm only 1 ½ hrs from Albany and go down quite a bit, and will be there over the Xmas Holidays. Does anyone know of a good Diesel Tuner/Mechanic in Albany ?? Doing a Google doesn't really bring up much, and then again I'm asking here because I want first hand knowledge.
If anyone can tell me where to go down that way, I would be very appreciative.

Cheers

Google Albany four wheel drive club and ask them if they can recomend anyone. Bound to be a few diesel owners in the club.
