Default Egr ???

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.

Maybe I should have posted this in the tuning section? I figured that was mostly for the LS guys.

Changed map cell boundries back to stock and it stopped. I don't get it.
