The Process of Deleting an L5P Duramax:

  1. You will require an HP Device, Canbus Plugs, and an Unlocked ECM.
  2. With the HP Device perform an Info Log before removing the ECM for unlocking.
  3. Remove the ECM and send it in. We will provide an order number for you if you purchase the unlock here.
  4. Once you receive the unlocked L5P ECM read the tune using the HP Device.
  5. Email us the stock tune and we will email you back the deleted file and get credits loaded (if purchased).

TCM tuning is only available for 8 speed transmissions at this time.


These tune files are custom written for your truck allowing safe and efficient power. With custom tuning you have the option to select a power level or leave the power level stock with emissions removed. 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.

Why delete your truck?

The DPF, EGR, and SCR systems on your 2007+ truck are complex, prone to depreciating and loosing efficiency, or outright failing and costing money to replace.

Many a modern day diesel driver has experience of a truck in reduced engine power, limp mode or not starting because of issues with the emissions systems on their truck.

A custom tune will allow the DPF filter to be removed, and turn off the EGR and SCR systems, allowing them to be removed and bringing back reliability to your truck.

Diesel and performance enthusiasts will grin with the power gains possible through tuning, and appreciate the ability of a skilled tuner writer to properly configure other aftermarket modifications like bigger turbos, injectors, built transmissions, higher capacity fuel pumps, cold air intakes and exhausts.

Transmissiong tuning for line pressure changes strongly suggested for 75hp+ tunes
