common sense might tell you to go to a shop and get dynoed to see what your a/f ratio is.

how do you know your running rich? do you have a wideband?alot of people mistake it for the smell of the o/r midpipe.

How do you know it's running crazy rich? Is your nose that accurate? But no, when it gets cold as a witches titty outside, your fuel mileage is going to drop for various reasons. When did you get the tuner?

MJH, thats a great line...cold as a witch's titty. But o/r pipes will make you smell like youre running rich, especially in the winter cus your fuel mix is running rich already. So thats probalby the reason why. Or your tune might be a little rich for the winter use. just a thought.

You're just over-thinking this. So your exhaust stinks?

Here's what you do. Throw it up on a dyno and you will see the A/F ratio in the 12-13 range, then get on Ebay and order the right foot mod. Then you can rest assured your car is ok.
