GM's 6.6L L5P Duramax is an exceptional V8 turbodiesel engine. Its remarkable output of nearly 4-digit torque and 445 horsepower underscores its serious capabilities. While this engine is already impressive as it comes from the factory, many diesel enthusiasts are eager to explore its full potential, which is far from realized off the showroom floor. Fortunately, there are tons of superb performance upgrades designed for the L5P Duramax. When it comes to handheld tuning devices with ECU unlocking capabilities, the Edge EvoHT2 is certainly in contention to be one of the best.

Flash tunes for the 2017+ GM Duramax L5P have been tricky up until recently. In order to tune the factory ECU, it first has to be unlocked, which is typically a challenging task that includes removing the ECU, digging through engine wiring, or swapping the ECU altogether. Luckily, Edge, one of the premier and respected diesel tuning brands, has solved that problem with the EvoHT2 L5P handheld tuner. With the EvoHT2, forget all of the hassle, as it is a complete plug-and-play flash tuning solution for 2017-2019 GM diesel owners.

The L5P Duramax EvoHT2 is a remarkable tuning option that delivers tremendous power gains of up to 150hp/350tq to the tires. It also enhances throttle response, accelerates turbo spool-up, and boosts fuel economy, while giving you complete control over your driving experience. Thanks to its 'Remember Last Setting' feature, the EvoHT2 allows your truck to store your Tow/Haul, Grade Braking, and Exhaust Brake settings automatically every time you start your vehicle. The device is incredibly user-friendly, featuring a simple interface, color screen, and stunning visuals. With four pre-loaded tunes, it caters to every owner's unique requirements. Whether you aim to improve your daily driving mileage, towing performance, or even burn some rubber, the EvoHT2 is the perfect solution. With Edge flash tuning, you can unleash the full potential of your L5P engine.

Do I need to leave the Edge EvoHT2 plugged in all the time?
You are not required to leave the EvoHT2 plugged in at all times. In the event you want to change your tunes, you can use the Evolution to do so, and then unplug it and store it until you need to change tunes again.

Does the 6.6 Duramax Edge EvoHT2 have support for custom tuning software like EFI Live?
Unfortunately, the Evolution CTS3 does not support custom tuning with aftermarket tuning software like EFI Live. You are able to select from the four preset tunes included with the device.

Does the 6.6 Duramax L5P Edge EvoHT2 support DPF deletes?
The 6.6 Duramax Edge EvoHT2 does not support DPF Deletes. Edge Products complies with all emissions standards and doesn't manufacture any equipment to delete DPF, EGR, or alter emissions equipment.

With that being said, the EvoHT2 offers the option of manually regenerating your DPF system, which enables you to perform this task at more convenient and optimal times. By using this feature, you can maintain your DPF system more effectively and avoid the hassle of making annoying trips to the dealership.

Can the 6.6 Duramax Edge EvoHT2 be used on multiple vehicles?
If you own several vehicles, you cannot use the Edge EvoHT2 on all of them simultaneously. This is because when you connect the programmer to the OBD-II port, it synchronizes with your truck's unique VIN number. However, you can use the programmer on another vehicle after returning the original truck to its stock settings.
