[QUOTE="4vmn12, post: 11244167, member: 37414"] in case it wasn't already clear you do have to remove the EGR valve, and block the hole. It seems that is a foregone conclusion since it is removed to clean-up the engine bay. On older applications the tube would be disconnected, and the EGR valve was just left on the back of the intake with an open pipe connection (until a more permanent solution was put in), the tune could be commanded to disable the valve which effectively closed the valve. If this was not done the valve could open and let unmetered fresh air into the motor during cruising...... Wooops! Lastly, there were some earlier year mustangs/fords (possibly even a Cobra don't remember what year possibly 1996-1998 range), which used an air pump for emmissions instead of EGR. That would be the only form of EGR I would use, but I doubt the emmissions / gas mileage are worth the expense/time/complexity of implementation. Some owners on here barely put 5k miles a year on their beasts! [/QUOTE]
