The Shift on the Fly (SOTF) Switch is the easiest way to switch through your tune files on the go. Without a SOTF Switch, you'll need to use your EZ-Lynk or EFILive device to flash a new tune into your truck. If you're choosing a device with more than one tune file, we highly recommend adding one of these switches to your package!

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 in the event of a failure.
What we recommend:
EGR Blocker Plates: This is what we will recommend to the majority of our Duramax customers who are wanting to delete their truck. This option will give you peace of mind knowing that if the EGR valve fails, you will still be preventing the EGR gasses from recirculating.
EGR Delete: This would be recommended for those who are planning to make big power, or looking to completely get rid of the EGR system from their truck. In turn, this will clear up room in the engine bay, which can come in handy while performing maintenance and/or upgrade
Note: For a Full EGR Delete, the EGR Delete kit will have to be paired with an up pipe, this up-pipe can be found in the next category.
