Don't know of a good tuner here in Nashville, as I haven't needed the service. Maybe look at and contact some people who are a part of the Tennessee SCCA, trscca.org. What is your end goal of your project? Just wondering how to best help you out, if making it a daily, autocross, road racing, drag, or other. I use to be a technician for Land Rover and other places, so have overall knowledge, but not great for things like Mega Squirt and the likes. I have a 1975 280Z and slowly working towards it being a track vehicle, mostly geared towards autocross.
I too moved from California a few years ago. Grew up Fresno, but lived in Rancho Cucamonga, Anaheim, Roseville area and Colfax before moving out here to Nashville area. Definitely hit me up with any questions I might be able to answer or meet up once you head out this way.
