EGR and ses light

Hi all:

I have a 94 T/A with a M6 and 3.73 gears. I get alot of SES codes for the EGR. If I cruise at 55 to 60 in 6th, I'm only tacking around 1300. And yes it is flat where I live, but the SES will come on alot, and go off after awhile. I know the vacuum operated EGR is not the best design, but wanting to know if there are any tips to eliminate this. I don't want to delete it, but get tired of seeing it come on. I know my aftermarket exhaust is causing it, but looking to see what anyone can recommend.

You could lower the "EGR Enable RPM" in your tune.
