My 96Z seems to be running rich after installing headers and cat-back. I'm going by the smell test. I just don't remember it smelling so rich before. Would I benifite from a tune? If so what kind of price am I looking at?

Thanks,
HF

 

Check your O2 sensors and for stored codes. I wouldn't think exterior mods like that would affect factory tune. It seems there might be another problem. Maybe one of the 'master mechanics' here has more input.

 

do you still have a cat b/c if your like me and ditched yours mine smelled a little richer after that

 

Sure do. Still have both factory cats in there. Car isn't showing any codes.
