We've revamped our tune file processing system! After you place your order, you'll receive an order confirmation email that includes a tune form to fill out out your vehicle. You can also view this at the top of the website. This helps us get all your tuning information in one place to process it quickly.

** Important Notes: 
  • This requires a 2019 - 2021 model year PCM. Stock is limited on our side as they are hard to get right now. Typically these p/n will start with a "4" and the D/C date will be 2019, 2020, 2021.

    • Note:  New PCM's from the factory (not programmed), can be used in rare circumstances. This takes additional programming on our end. Which leads to additional costs.

  • Skimm data is transferred with the MM3 Device. Please allow a couple days to complete this process

    Cummins CSP4/CSP5 Pass Through Switch:

    CSP4/5 pass through switch allows you to change power levels on the go, or commonly referred to "Switch on The Fly". They do NOT require you to stop the truck and wait 5 minutes for the truck to re-flash, you just turn the rotary dial to the position of the tune you want while the truck is running or driving down the road and carry on. These switches plug into the OBDII port and have a pass through port allowing you to plug something else with a OBDII plug into it, such as a Monitor.
