Thanks, good idea. I'll do that, though am a little skeptical of how realistic the sound via a computer is compared to the real thing. I'd rather hear a real Mustang V6 with true duals. BTW, Chris B., I think the place you were referring to is ProDyno. http://www.prodyno.com/Home/ I also had the same referral from Kustom Koachworks where I've had some excellent body work done.
