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.

Adding an intake isn't about power, it's about reducing the restriction, increasing efficiency, while maintaining strict filtration standards. These kits are offered with a Oil Cleanable Filter and Dry Disposable.
The Oiled Filter is recommended for those that mainly use their trucks for City or Highway driving and would rather clean their filter instead of replacing it.
The Dry Disposable is a better option if your truck frequently sees dusty environments or you'd rather toss out your filter instead of cleaning it.
