Full EGR Delete - Why?

I can see protecting the longevity of the engine. I get that. Are there any other reasons?
  • Does the turbo spool quicker?
  • Do you get more turbo whistle?

I heard these mentioned - but no one has given a definitive "YES."

Last but not least - do you need to add a wastegate when deleting the EGR?

One benefit of deleting the EGR, opposed to block-off plates, is to prevent carbon build-up on the EGR valve. I've heard from people with first-hand experience that you do get more turbo whistle. This probably occurs due to turbo being exposed once the EGR is removed. I haven't heard anything about the turbo spooling faster and I wasn't aware that deleting the EGR affected the wastegate. I don't know much more than that and I haven't deleted the EGR on my truck, only block plates.

Thanks for the comments, guys. My 6.4 had a little more giddy up off the line after I deleted the EGR. The turbos were always loud in the cab. Not outside like on the 6.7.

"I've heard from people with first-hand experience that you do get more turbo whistle. This probably occurs due to turbo being exposed once the EGR is removed."

This makes sense.

"Lol what is with the turbo whistle??"

Just love that sound!

I didn't notice much difference with mine fully deleted vs. unplugged. I did it for the health of the motor.

How much healthier is fully deleting vs. block plates? Does your delete kit still recirculate coolant?

The sinister kit does recirculate coolant, but I'd be lying if I tried to tell the benefits of block offs vs full deletes.

Nice. The coolant is good. I think one benefit has to do with build-up on the EGR valve. I don't know. I guess you free up more space with the full delete too.
