i think my truck already has a egr delete and up pipe but need some help

i just bought a 2006 f-250 and i was looking under the hood today at my up pipe because it whistles after you start building up boost but anyways it looks like the bottom clamp is loose but i noticed that the up pipe just goes straight up with nothing coming into it from the egr so i looked at the egr and it looks like a egr delete kit has been installed. The thing i was wondering about is that the egr valve is still installed (no block off plate) why is this and is this why my throttle response is not as good as my friends trucks that have the egr delete

i will upload some pics in a few min

So it still has an EGR cooler but no connection at the up pipe? Or it's got a delete on it?

If you have something whistling then you probably have something leaking off, which will cause less throttle response.

Yeah, any pre turbo exhaust leaks can make a noticeable difference in boost and overall power. Glad it seems better!

Some(maybe all???) 05 and newer trucks with the EGR cooler delete need the EGR to remain plugged in to avoid complications. When Matt from Gearhead wrote my tunes, he reminded me to keep my EGR plugged in when I do my delete. Some guys leave it in the intake and some pull it and let it flop around on top of the motor. Mine will remain in the intake.

No, it's not blocking anything because there is no more EGR flow thru there. If you don't have a tuner that deletes out the EGR valve function leave it in there. The only time I remove the valve is when I install a tuner like a SCT tuner that turns the EGR valve function off.

Some people have had issues with just unplugging the EGR valve. It can cause the fan to not operate correctly.
