if your stealth is awd then any place will do a no load test from the tail pipe. nobody's gonna hook up the obd2 connector if they see the R vin code telling them it's a 94. i'm not sure what you should set your safc for to do a "no load" test, i'm not a tuner nor do i know the mods you have on your car to suggest what the safest/best thing to do is. my suggestion to you is if your safc's already tuned for your car/mods don't mess with it. there's a place called meister lee on terrell mill road right where it meets with cobb parkway that only charges $20 for their emissions tests (some places charge $25) i go there for mine. basically i'd change the oil, put some 93 octane in the gas tank then go up there and get it tested once the car's warmed up. if you fail, post what you failed on and what was allowable, then we can help troubleshoot you for what you should do, once you make the alterations then you can go back for your free retest. good luck =]
