Service Process - What to Expect
For 1996-2003 Model Years:
You will need to remove and ship us your Engine Control Unit (ECU/ECM) for reprogramming. Our technicians will perform a complete flash tune optimization on your unit and return it ready to install.
For 2004-2007 Model Years:
You will need to remove and ship both the Engine Computer (ECU) and the CPC Controller (Coordinated Powertrain Controller). This dual-controller system requires synchronized programming for optimal results.
Why we tune the CPC Controller: The CPC controller manages critical torque limitation tables and communication between the engine and transmission. By tuning both units together, we can:
- Unlock power gains while maintaining safe torque limits for automatic transmissions
- Adjust speed limiters to your specifications
- Ensure proper coordination between engine output and drivetrain capabilities
- Protect your transmission from excessive stress
Turnaround Time: Typically 1-2 business days from receipt of your units. We understand downtime costs money, so we prioritize fast, efficient service without compromising quality.
