Dru-TuRn

I live in OKC, and after 2 months of ownership, I finally went to put my E63 S on the Dyno yesterday. But when I got there, I noticed it was a 2WD dyno, and the guy told me there aren't any AWD's anywhere in OK. So question number 1) is there a (reputable) Dyno in OK I can take my car to, or 2) where is the best place in Dallas for a Dyno run, and probably a light tune?

For the record, I should've asked if he could handle my car BEFORE I made the appointment, but this place came recommended by a friend of mine, so I figured he would've said something.

Try AWD Tuning in Dallas. They won't tune though. Closest place that will that's worth going to is in Austin.
