Okay^ thanks. But so I'm buying Buickboys old OBX header soon hopefully, if he ever sends me a pic, but he said it had two holes, one for a wide-band, and one for the o2 sensor.
Where is there o2 sensor that is staying? Is it down after the cat, and the wide band sensor is up top on one of the tubes?
Just trying to get a basic layout in my head for how this set-up is sopose to look, and where everything is located, I know the EGR system will need to be deleted too, and I know how-to on a Zetec, but how is it on a Duratec?
I seen before that it has a tube that comes off of the intake manifold, and connects to the sensor on top of the thermostat housing, and then runs one more line to the tube coming off the header that will be gone, so is it as easy as block the little hole on the intake manifold and get the tune?
