GM Engine EFI Tuning Service - Factory Controller

Unlock the full potential of your build with our custom EFI tuning service. Whether it's a daily driver or a full track setup, we dial in your engine for power, reliability, and drivability. 

What's Included:

• Full custom tune tailored to your engine, mods, and fuel type
• Dyno or street-based tuning (depending on option selected)
• Data review + fine-tuning for drivability
• Support for bolt-on or built engine combos
• HP Tuners and more supported platforms

Boosted or Nitrous?

If your vehicle is supercharged, turbocharged, or running nitrous, please make sure to add the Boosted/Nitrous Tuning add-on to your cart. This is a separate service and is required for proper calibration of forced induction or nitrous systems.

How It Works:

• Appointment Required - All Tuning is by appointment only
• Deposit Needed - Non-fundable deposit required to book
  
• Remote Or In-Person - Ask us if your build qualifies for remote tuning

Ready to get the most out of your setup?

Once you complete your purchase of the EFI Engine Tuning service, please book your tuning appointment using the schedular at the bottom of this page to reserve your slot.

ECM Unlocking: If your tuning setup requires work on the ECM (such as unlock in person, exchanging, or sending one in), we'll take care of it after your purchase.

Once you complete your order and select your tuning options, we'll reach out by email or text to go over the next steps. This may include:

• Sending your ECM in
• Coordinating an unlock service
• Arranging an exchange or replacement

We'll guide you through the process based on your specific vehicle and setup to keep things simple and efficient.
