DURAMAX Tune Files

Description

Please note that these are Duramax tune files only. A VIN License will be required if your EFI OR HP TUNERS device has flashed another truck.

These tune files are custom written for your truck allowing safe and efficient power. Custom tuning can also be modified for performance modifications such as larger turbos.

Multistage custom tuning allows you to select the best power level for your application. For example, a tow tune will provide a wider torque curve to assist with a heavy load. By having selectable tuning, you can maximize your fuel efficiency or power where needed or for fun.

Transmission tuning, where applicable, is recommended to increase the transmission’s ability to handle more power by increasing line pressure and moving shift points.

Multi-stage are generally:

• • 0hp Stock Power
  • 25hp Tow (With brake if LLY+)
  • 45hp Economy
  • 75hp Street (transmission tune suggested)
  • 90hp performance
  • 120hp Race

Transmissiong tuning for line pressure changes strongly suggested for 75hp+ tunes
Transmission tuning available for LWN and LML Duramax’s
