L5P Tuning Package
Take your L5P to the next level with custom tuning! L5P Tuning Package includes everything you need to tune your 2017 & 2018 L5P Duramax. No need to delete your exhaust or tamper with emissions equipment to get the best performance out of your truck. Our L5P Tuning Package unlocks the power potential that you paid for when you bought the truck from the factory.
While the rated horsepower for the L5P is 445 HP and 910 ft-lbs of torque it dyno'd 405 Rear Wheel Horsepower (RWHP) and 850 ft-lbs on our loaded chassis dyno. This is an improvement from previous models but if you have ever driven a diesel truck at 500+ RWHP you will immediately notice the difference.
This package includes:
- HP Tuners Unlocked ECM
- HP Tuners Unlocked TCM
- HP Tuners Unlocked MPVI2 cable
- HP Tuners Universal Credits
- DuramaxTuner.com's ECM Tuning
- Tow Tune (+80 RWHP)
- Sport Econ Tune (+180 RWHP)
- DuramaxTuner.com's TCM Tuning
- Increased clutch holding capacity
- Improved shift quality
Our extensive testing of the 2017 - 2020 Duramax powered 2500/3500 HD pickup truck has given us powerful insight into this platform. We took our time to completely understand the system and how our tuning would impact performance and reliability. Whether you are towing, commuting or just daily driving your truck we know our calibration is going to be safe and completely satisfying.

HP Tuners Disclaimers:
NOTE: Note this ECM exchange service is completed at the owners' risk, HP Tuners will not be responsible for the vehicle, its power-train or electronics, nor how the ECM is used, calibrated and its functionality. Should you experience any issues with your ECM, please contact firstname.lastname@example.org for assistance and how to proceed.
A reminder that your ECM will not be returned to you, this service is an “exchange” and you will receive another modified ECM in its place. There is no outright purchase option available at this time.
We exchange and modify ECMs as fast as we can, but initially, please allow at least 3 business days (plus the time to ship the ECM) per ECM that you send in for the exchange process to be completed.
