Gumby.As for getting better performance when EGR not working. From what I understand is that the timing will be retarded if motor is pining. So not hearing the ping could mean that it runs fine without the EGR or the timing is retarding. I don't know if you can check timing at the rpm that is needed to open the EGR?? If so then you could check it.
