2001-2004 LB7 Duramax Custom Tune (HP Tuners File-by-Email)

Custom calibration for the 2001–2004 LB7 6.6L Duramax built on the HP Tuners platform. The LB7 is not supported by ezlynk AutoAgent, so this tune is delivered as a custom-built HP Tuners file matched to your specific truck.

How it works

1. Place your order.
2. Email your stock (unmodified) HP Tuners read file for your LB7 to nanotorquesolutions@gmail.com, along with your order number.
3. We build a custom tune calibrated to your truck and email the finished file back to you.
4. You flash it to your ECM using your HP Tuners MPVI interface.

What's included

• Custom LB7 engine calibration tailored to your truck and modifications
• Multiple switchable power levels
• Datalogging support for ongoing refinement

What you need to provide

• A stock HP Tuners read file from your LB7 (we'll email instructions if you're unsure how to pull one)
• Your truck's modification list (injectors, turbo, fuel system, etc.)

Requirements

An HP Tuners MPVI interface and a valid credit balance on your account are required to read your stock file and flash the finished tune. This product does not include the HP Tuners device or credits.

Support tiers

• Limited (4 Weeks): Four weeks of revision rounds after initial file delivery.
• Full (Lifetime): Unlimited revisions and lifetime access as your build evolves.

All calibrations are developed for emissions-compliant performance and must be used in accordance with applicable local, state, and federal regulations.
