When purchasing Emissions-Off tunes, the new delete 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.
Please be sure to input your VIN and Modifications at the bottom of the page so we can have the custom tuning written as soon as possible.
If you're 'delete tuning' your truck, you'll need an exhaust system.
3" Delete Pipe
Note: These do require a substantial amount of work to get the OEM system out of the truck. Installation is only recommended by a certified shop.

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.
