Well there is always Matty Spry, (do a search in the qld section for his number, he's on the Gold Coast). But again he is not cheap.
I have heard from lots of people that Matty really knows what he's doing. Also I have spoked with heaps of people who have had their car dyno tuned at MM, and none report anything bad.
I had my old r33 tuned there and was more than happy with the outcome, wasnt a PFC tune though, just a SAFC, but was worth it alone just for the petrol consumption saving!!
