2001–2010 Duramax Custom Tune (EFI Live)

This custom EFI Live tune is built specifically for 2001–2010 Duramax trucks, delivering smoother drivability, improved throttle response, and refined power delivery tailored to your exact setup. Each file is calibrated from scratch using EFI Live software—no canned tunes, no shortcuts.

Whether the goal is daily drivability, towing confidence, or a more responsive truck overall, this tune focuses on reliability first while unlocking the performance these platforms are capable of. Adjustments are made to fueling, torque management, and transmission behavior where applicable to create a balanced, predictable driving experience.
