I've had one tuned on the dyno before with Kalmaker $700. Mail order from www.memcals.com and another from a person on eBay goes by the name nicefrog. Both were as good as the dyno tune. Both of them are well known on the forums both mechanical and the tuning.

Memcals.com known as Chip doctor on the forums $300 and nicefrog known as Greenfoam on the forums was $150.
