READ EVERY STEP BEFORE YOU MAKE ANY MODIFICATIONS TO YOUR TRUCK.

You do NOT need the TDN app — follow the instructions below.
All emissions equipment must be installed, functioning, and free of codes or errors.
Ensure the DEF level is not low.
For 2017–2019 models, soot level must be below 70% before beginning.

The tuning process cannot start until your order has been delivered.
You will need to install VCM Suite BETA software.
Always confirm you have the latest BETA version every time you open the software—updates are frequent.
After installing the software, use our guides to gather the files required for us to build your tune.

Use the guides below to complete the read and write process needed for tuning.

Always use a battery charger capable of supplying a STEADY 10 AMPs or more.

Always close the file when opening VCM software (top left Folder icon)
The current VCM Suite Beta software requires a certain version of .NET.
If you receive software errors, verify or update your .NET installation via the HP Tuners Downloads page (under the BETA software link).
If emissions were unplugged before tuning, you will likely get a Service Emissions message on the dash.
If the DEF tank was low at the start, you may see a Low DEF message after tuning.
To avoid this:
- Keep DEF at least ¼ full
- Ensure soot is below 70% on 2017–2019 models
- If soot exceeds 70%, perform a forced regen before tuning
