I'm sure
Monkeywrench Racing Home Page in Houston could help you out, but I've no idea on their prices for that sort of thing.
Look online for dyno tuning in the austin area. I'm pretty sure there is somebody who does that near you, but the name escapes me. They would have an idea for local shops.
Henderson Performance Technologies Location
New braunfuels dyno/speed shop. Website looks domestic focused, but they show a picture of doing a corvette swap, so I bet they could help you(and closer than houston, just go down 35).
