Edge Products Adds 150 HP and 350 lb-ft Of Torque To The LP5 Duramax

Since its 2017 debut, the L5P Duramax has gained quite the reputation for being a tough nut to crack, in terms of tunability. The bulk of these difficulties was attributed to the complexities of the L5P’s ECM, which proved far more difficult to unlock than many other controllers have historically been.

Though tuning of the L5P did, in fact, prove possible, doing so typically involved removing a truck’s ECM, so that it could be manually unlocked to provide accessibility. The downside of this proposition was that the ECM in question had to be shipped off to a third party, for this service to be performed. This left consumers at the mercy of the shipping industry and necessitated an unspecified length of downtime.

Luckily, Edge Products has engineered a creative workaround, allowing L5P owners to tune their engine’s performance, without so much as touching their ECM. The Edge EvoHT2 connects to the OBD-II port of any 2017 and up Duramax-equipped GM truck, making use of the Edge’s proprietary Locksmith adapter.

Once connected, the Edge EvoHT2 can be used to select between a handful of heavily tested tunes. Some of the most noteworthy of these preset tunes include Light Towing mode, Heavy Towing mode, and Extreme mode, the latter of which provides performance gains up to 150 horsepower and 350 lb-ft of torque.

In addition to the tunes listed above, users are also furnished with a specialty Economy mode tune, which minimizes fuel consumption, without any noticeable loss in performance. Several individually customizable settings menus can also be accessed, such as those which allow throttle pedal sensitivity to be adapted to user preferences.

Aside from its numerous tuning-related functions, the EvoHT2 proves capable of resetting and calibrating a number of vehicle functions, most of which would otherwise require a visit to the dealership. In this regard, the EvoHT2 is quite likely to pay for itself over the course of ownership.

The EvoHT2 can be used to calibrate stock speedometers, providing an accurate visual representation of speed, and eliminating the delivery of skewed speed inputs to a truck’s ECM/TCM. This comes in extremely handy when installing larger aftermarket wheels and tires on lifted trucks.

Additionally, the EvoHT2 can be used to modify a truck’s TPMS thresholds to eliminate erroneous tire light messages, during seasonal temperature shifts. The ability to modify these settings is also perfect for those who wish to inflate their tires to specific pressures that fall outside of the stock inflation rate specified by GM.

Also noteworthy is the EvoHT2’s ability to save and catalog the LP5’s stock tune for later use. This prevents any worry over being unable to return your truck to stock settings if such a need ever arose. To an extent, this should alleviate the bulk of anxiety surrounding future trips to the dealership, when attempting to have unrelated warranty concerns addressed.
