Calibration · Controller work · Remote tuning
Start with the vehicle, controller, or job.
PCM Tuners handles calibration, remote tuning, mail-in work, unlock and access preparation, VATS, and controller requests. The right path depends on the exact application—not a generic service label.

Choose by job
Use the shortest route to the right answer.
Vehicle first
A tune or package for a known vehicle
Start with year, make, model, and generation so the service and hardware stay tied to a real application.
Controller first
Unlock, access, VATS, donor, or module work
Choose the GM or Mopar branch before ordering. Controller family and current state change the workflow.
Hardware first
You already own a compatible interface
Use the hardware chooser to confirm the device, then select the matching tune or service path.
Uncertain application
The vehicle or job does not fit a listed path
Send the exact details before buying. We will confirm whether the request fits an existing product or needs a custom workflow.
Before you contact us
Bring the details that decide the workflow.
- Year, make, model, and trim
- Engine and transmission
- PCM, ECM, TCM, or controller information
- Current hardware and unlock status

Still not sure where to start?
Do not guess at the controller, cable, unlock, credits, or device. Send the application first and let us route it.
