RustyRockets

I have a heavily modified 280z with a turbo and a megasquirt computer. It's a car that I bought from someone else a few months ago and
In general the car runs well (240hp on the Dyno) but it should be getting more and there is an issue with oil consumption when under heavy boost (12psi). I don't think it's burning the oil and also the catch can is pretty empty.
I'm definitely in over my head as far as troubleshooting abilities.

I'm looking for a solid shop near Orlando to sort the car.
Definitely they need to have performance tuning experience on older Japanese imports.
Even better if they have specific Datsun knowledge.
Reliability and ability to "get it done" is more important than price.

Any suggestions?
