EGR Differential problem

I didn't. I'll give that a shot tomorrow possibly. I don't have INSITE or INLINE 5, but the way things have been going the past couple of months, it's high priority now. I had the EGR valve, backpressure sensor, and a couple other things replaced, so I wanted to pretty well update the rest of the system as best as I could. Since the EGR valve is controlled by the Diff sensor, would a malfunction of either one cause turbo lag? Before I got the MIL lamp, I could put it to the floor at 55 and would only get 5-10psi boost sometimes. I put the old one back on, and haven't had any boost issues since. Forgive me if these are basic simple questions. Just trying to get a grasp on this 2250. Thanks!
