Need to find a Dyno in the Maryland area

[Methodical]

I want to put my car on a dyno to see where my tune is. I don't need a dyno tune just dyno sessions. From what I understand there are different kinds of dynos so which is the better one and which should I stay clear of. I want the most accurate readings.

Thanks

Justins Performance Center (JPC Racing) is in Glen Burnie, about a 45 minute drive.
