tune = smelly exhaust?
I have a Superchips installed in my car. Believe my speed shop tuned it to be a little more lean to get a few more horses. Now I have to run 93 octaine gas, and it seems my exhaust stinks a little. Does that happen with an aftermarket tune like that? I do have high flow cats on so there should be no smell at all. Is this normal?
