I bought an eec tuner for my 91 sc after adding just about every bolt on. When i had it on the car it made it run like crap but when i took it off it ran much better. I still want to use it so i can get a file from Dr. fred and also to adjust for the #42's injectors and my rich problem. What is the reason that the tuner is makig my car run bad? Is it the wrong one for my computer? If so then how or can i change it?
