GM Mail Order Tuning

GM ECU mail order tuning service

Mail order tuning allows PCM Tuners to modify your GM ECU calibration directly. Instead of using remote tuning hardware, you send the ECU to our shop where the calibration is updated and returned ready to install. This option works well for stock vehicles, mild upgrades, and customers who prefer a simple process.

When mail order tuning makes sense

• Stock vehicles needing performance tuning
• Basic bolt-on modifications
• Vehicles without remote tuning hardware
• VATS delete combined with tuning
• Customers who prefer shipping the ECU instead of logging

How the mail order process works

1. Place the mail order tuning service order.
2. Remove the ECU from the vehicle.
3. Ship the ECU to PCM Tuners.
4. Calibration updates are performed.
5. The ECU is returned ready to install.
