Tuning OBD 1 cars has become more challenging to say the least. I have never had much luck with dyno tuning. Keep one thing in mind when you go for a dyno tune; a dyno only tunes the car for wide open throttle, it does nothing for driveability. The only way to get good "street manners" is to deal with someone with a lot of experience. The current tune in my car was purchased from JMS in 1999. Stock Mustangs have less street manners than my car does. When I dyno tune the car on motor or on the bottle, I adjust fuel pressure and base timing. I have never had a chip reprogrammed. The last car I did, we searched the earth for someone who had any knowledge on how to do a chip. Guess where we ended up, back at JMS. The Cobra idles like a stock Mustang with a .544" lift, 512 sep. cam in it.
My advice on the dyno tune issue: If you have a serious street race car, and you are dying to get that extra 5hp out of it, spend the $1000 for a dyno tune. If this is a car you actually want to drive around (as opposed to one you drop off a trailer and run a 1/4 mile with), save your money and get a chip sent to you in the mail.
