Anyone know of a location in Austin (or near Austin, Tx.) that has a Dyno and/or might be experienced in installing performance upgrades such as headers and exhausts on Acura?

I'm heading down that road looking for more horsepower and really need an accurate way to quantify where I am starting, and also need a way to reliably record what results each of my modifications might bring.

It would be really nice if I could get HP tests from the same group of people who are responsible for successfully implementing horsepower improvements.

Any suggestions and explanation of experience with your suggested shop will be appreciated.
