No Catalytic Converters

Hey 370z tuners, I have some questions about tuning. First, when I bought my car, the previous owner had removed the catalytic converters and put Z1 test pipes on the car (I live in the part of Virginia where we don't have emissions tests). Since I have gotten the car, I have put cold air intakes and AAM resonated short tails on the car. So I was looking to get a tune. I have never had a car tuned before, so this was going to be my first experience with the whole thing. I contacted a tuner, and set up an appointment and told them about my setup. They said they could do it. Today they call and say they can't tune a car without catalytic converters because of their policy, and offered to install some for about $1200 or give me a refund. I took the refund.

So my questions are:
Can a car be tuned without catalytic converters?
Am I ruining my car by not having them?
Does anyone know a good tuner on the central East Coast that would tune a car without cats?
If I do get cats, which ones should I get to make the most power?

Thanks!
