Fuel Injection Specialties in San Antonio has a Mustang Dyno, it gives you all sorts of info. My friend Rudy works there, he works on engine harnesses. He told me a few weeks ago, some guy came in from North Carolina to Dyno 12 Stangs in one day. I know they have a site. I cant remember how much a session costs butif i find out i will post it.
BTW, what do you plan to dyno?
