EGR enabled/disabled - stumped

Has anyone else notice less low end power after doing the EGR cooler delete with new up pipe?

Seems that after my egr cooler was deleted and the new up pipe kit installed I have less low end power with tunes that have the EGR disabled. I notice the pedal feels looser, not as hard to push down, kinda sloppy.

After the install, I played around with some tunes and noticed when I run a tune with the EGR enabled, the low end power is back and my pedal is stiff and has better throttle response. So is my strategy looking for my EGR to be on? I just don't get this. It's a noticable drivability difference with the EGR on/off, eventhough it's just a valve hanging there with nothing going to it. I notice my injectors sound louder as well with the EGR on.

I loaded a tune with the EGR on, runs great. Then unplugged the EGR and it acts just like the tunes with EGR disabled, low end power not as strong, .

Anyways, truck runs great on custom tunes with EGR enabled, just can't understand why having it disabled would act like this.
