get you an inline adapter off flea-bay for a few hundred bucks, a copy of Insite going on a cheap laptop, and look at the regen history.

Post some screen shots of the regen history for some advice and opinions.

Thanks for the reply, I have insite, and have been studying the egr tuneup. I will get on it. I just took the front of our combine apart so it may take a week or two. I really appreciate your help and website.
