And finally, what is with these "Mil" eliminators, I have never heard of them, although I can assume what they do, is there a place that explains how they work, and where I purchase them (if indeed I purchase them and not do it myself) thanks for your help guys!!!!! -Nick
Gutting the cats will not change the air/fuel mixture, so you shouldn't have to worry about running lean. The PCM compensates pretty well for most of the basic mods because the MAF remains directly in the intake path keeping track of how much air your motor is eating up. You will need MIL eliminators for the downstream sensors because there will be no difference from the upstream sensor and the computer will figure out that the pre-cat isn't doing it's thing and set the CEL. I think a couple guys sell them or there is a mustang site that has links to a supplier. Try a search for MIL and you'll get lots of info.
