I have EGR tuned out on my 95 TA but in certain cells, I see it being commanded on/off real fast. I can't figure out why it's even trying. Anyone have any thoughts? I've never had this problem in the past.

 

I usually just change the EGR min and max RPM constants and that does it. I started with that and went as far and changed all constants to unrealistic numbers. I also zero'd out the spark correction table. I have a feeling this is contributing to my cam surge although I can't find any evidence to prove it. Last night I changed my cell boundries to help with tuning so it would use more cells and the EGR was commanded more often and cam surge go worse.
