I know that a similar thread has been started, but without much success. I'm interested to know what anyone else knows about auto performance shops in the state of Missouri.

Thanks

I recently contacted Mustang Muscle in High Ridge, down off of Hwy 30 (Gravois Rd, west of 270).
He said they have a dyno, and a special on the first Saturday of each month where you get 3 dyno pulls for like $45, instead of the normal $60.
Sounds like a great deal.
He also mentioned that they have had good luck getting power out of the GM V-8's, more so than the Mustangs they specialize in.
I'm definitely going to head down there sometime, hopefully soon.
