Have a picture? The EGR does not affect power in any way. At WOT the EGR is ordered closed by the PCM. The purpose of the EGR is to reduce combustion temperature at part throttle in order to reduce NOx emission, and to allow more spark advance for fuel economy. _____________________________ Pete (in reply to libertyforall1776) Post #: 5
