Specific Instructions
For 2007-2012 Cummins Trucks:
Important: Make sure to install the patch file before loading the tune. Failing to do so could cause damage to the factory PCM, potentially requiring a dealership re-flash.
Cummins Specific Instructions:
- Locate the intake air throttle valve on the driver’s side of the engine bay, under the intake, by the intercooler pipe.
- Ensure you “unplug” this valve. Leaving it plugged can cause it to stick closed, resulting in issues with engine operation or RPM behavior.
- If you are unsure about the location or the unplugging process, consider seeking assistance from a professional mechanic or tuner.
Duramax Specific Instructions:
- Prior to tuning, unplug the intake air throttle valve located on the passenger side of the engine, beneath the hood, next to the alternator.
- For LML 11-16 trucks:
- Unplug both EGR valves. The first is located on the driver's side, and the second on the passenger side.
- Also, ensure the intake air throttle valve is unplugged. Not doing so may cause malfunction or failure to rev-up.

Can I read the stock file with AutoCal?
No. The stock file cannot be read directly using AutoCal. If you need the original stock file, contact your dealership for a reflash to ensure you have the correct factory settings.
What happens if I damage the factory PCM?
Damaging the PCM can lead to significant repair costs and a possible dealership re-flash. Always follow the instructions carefully—especially for 2007-2012 Cummins models, where installing the patch file before loading the tune is critical.
