When purchasing delete tunes, the new programming will automatically close the existing EGR valve to prevent any gasses from being recirculated. This means you don't need to fully delete your EGR in order to reap the benefits. However, with this option, you are relying on the OEM EGR valve to maintain a seal that can cause issues if it starts to leak.
