The new 3.0-liter Duramax LZ0 diesels are impressive engines right out of the box, but even solid platforms can use a little extra motivation. DemonWorks decided to strap the Edge EZX module to their 2024 Silverado 1500 to see if real-world data matches the marketing claims. Instead of relying solely on seat-of-the-pants feelings, they utilized GPS performance meters at high elevation to capture the cold, hard numbers on this plug-and-play power adder.
Setting The Test Parameters
Before hitting the test road south of Salt Lake City, it was important to establish a controlled baseline. The test truck isn’t entirely stock, rolling on heavier 35-inch tires and breathing through upgraded PPE charge air components, all while battling thinner air at altitude. For this specific evaluation, the driver zeroed out the throttle sensitivity settings via the smartphone app controller. This step ensures the results reflect actual horsepower gains delivered by the module rather than just a snappier pedal feel, isolating exactly what the hardware brings to the table in raw performance.
Stock vs. Edge EZX Power Levels
The testing initiated with a stock baseline run to set the standard. The 3.0-liter engine managed a 0-to-60 mph elapsed time of 8.45 seconds. Switching the unit on the fly to power level three immediately dropped that time down to a flat 8.0 seconds. Once cranked up to level five, the truck actually fought for traction, experiencing noticeable wheel slip off the line. Despite the spinning tires hindering the launch, the truck still powered through to shave more time off, hitting 60 mph in just 7.8 seconds.
Analyzing The Real-World Data
While 0-to-60 mph times make for good headlines, the 40-to-70 mph passing metric often matters more for daily driving scenarios like highway merging. The stock truck took 6.4 seconds to cover that gap, while level five accomplished the same feat in 5.82 seconds. Crucially, the Banks gauge data showed exhaust gas temperatures remained incredibly stable across all power levels, hovering safely around 1,180 degrees even on maximum output. This indicates the unit adds fuel safely without causing dangerous exhaust heat spikes.
Result Of The Edge EZX Installation
This setup demonstrates that owners don’t need invasive, complex modifications to wake up these modern small diesel engines. The installation of the Edge EZX provided measurable, repeatable gains exactly where they count most for truck owners. It proves to be a solid, effective upgrade for those seeking reliable extra passing power without complicating the build.
