...2. Why is it that your gas millage goes up when you d-smog? I thought the purpose of these systems were to recycle the non-burnt gas back to the system to be burnt and then the catylic converter cleans up the emissions.
Most go up in mileage because the smog systems are broken or not hooked up right.
The extra real estate under the hood and the simplicity of what's left is nice, though.
