There is this one www.ayaracing.com which is in the GR area, or you could go to Paul's High Performance in Jackson. And if driving isn't a problem you could go to Livernois in the Detroit area.
The guy is an SCT dealer and has a Mustang dyno. So he does have the ability to tune you. I did a dyno run there last year to check my a/f ratio. But I can't judge how 'good' he actually is in tuning. I'd contact him with what you need done and you can see if he's good enough for ya.
BTW, I believe he only works Friday and Saturday. And if you do go there let me know so I can come and watch if that's alright with ya.
I think the charge was a bit over $100 bucks, it was long time ago, sorry. And as far as I know he used one of the oxygen sensor holes to hook up for the a/f test.
There's Baker Engineering in Nunica, off M104. 2 pulls for $50 there and a little extra for the sniffer. Its not a Mustang dyno but is by far a better place to take your Stang. I've been to both for some dynoing and I'd stay away from AYA.

I have heard about Baker, but I was told that they don't do tuning, just dyno runs. Also, what was it about AYA that you didn't like? You can PM if you don't want to bash them publicly. Thanks!
