I would ask on some mustang forums. Judging by the cars they've worked on on their site, seems like a pretty good place.
98.5 SVT
91 Escort GT (almost sold)
96 ATX Zetec (i brake to watch you swerve)
FS: SVT rear sway bar
WTB: Very cheap beater
CEG Dragon Run - October 13-15
that place is very good....i have been there(though not to have work done)a couple of times when i had my mustang....not sure if they have done any work on tours,but i'm sure they could tune your car for you...
