PSI Power Performance Modules

PSI Power modules deliver a clean, reversible boost to your truck or farm equipment, transforming under-powered drivetrains into high-performance workhorses. Engineered and tested in Newburgh, Indiana, these modules offer more torque, smoother response, and improved efficiency—no ECU reflashing required.

What Is a PSI Power Module?

A PSI Power module functions as an advanced aftermarket performance enhancer which integrates unobtrusively into your vehicle. The module intercepts the signals between the engine control unit and sensors while refining them but it does not modify or overwrite the original computer. This plug-and-play device enhances fuel injection timing together with boost pressure and other essential parameters through its optimization capabilities that preserve the original computer data. The system delivers 30 percent more horsepower with substantial torque enhancement along with fuel efficiency gains that reach between 10 and 20 percent without exceeding original equipment specifications. The easy installation process needs no cutting or splicing and you can reverse the system anytime to preserve your vehicle's warranty. A PSI Power module serves as an effective solution for reliable performance in diesel pickup trucks when you need it most whether you're working in rugged job sites or operating field equipment in extreme environments.

How PSI Power Modules Works  

The core component of each PSI Power module features advanced microprocessors which function as smart communication links between engine sensors and the original factory computer system. Once installed the module retrieves engine control unit data in real time such as rail pressure, throttle position and exhaust temperatures. The module implements optimized calibration maps which precisely adjust fuel delivery and turbo boost together with injection timing. The module dynamically adjusts various engine parameters to maintain efficient and controlled combustion by modifying them in unison.

When cruising or driving under light conditions the module reduces the mixture ratio slightly to obtain better fuel efficiency. During heavy towing or fieldwork operations the system adds more fuel while moving the timing to generate sufficient torque for steep inclines and dense soil conditions. The module operates under factory safety thresholds which keeps exhaust gas temperatures and turbo pressures and RPM limits at the levels defined by engine manufacturers. The module features an on-dash switch to choose performance modes that match your present duties between Economy, Towing, and Full Power settings. The PSI Power module enables smart reversible operations that lead to better acceleration and smoother throttle response while maintaining vehicle reliability.

Key Benefits of a PSI Power Module

The performance boost of PSI Power modules transforms standard diesel engines into heavy-duty power machines by providing substantial power and torque enhancements. Powerstroke drivers achieve a 30 percent increase in maximum horsepower and torque output which leads to better acceleration and towing power without exertion. The additional torque from the pedal provides crucial momentum and control when driving up steep grades in Class 8 vehicles or towing trailers with two-wheel drive pickups.

PSI Power modules enhance fuel efficiency through their optimization of fuel delivery and timing processes. The optimization of the combustion cycle through mixture lean-out at cruising speeds and enrichment under load enables drivers to obtain 10–20 percent better diesel fuel economy while agricultural applications see savings between 1–3 mpg. Operating costs decrease substantially through these savings which allow owner-operators and fleet managers to recover their investment within a brief period.

The system enhances throttle response together with driving performance. Turbo lag disappears completely because of precise signal tuning which enables immediate engine response during pedal acceleration. The system produces better safety during passing operations and trailer control and provides a more responsive driving experience. The module delivers power gains without producing any rough or unpredictable behavior because it provides smooth reliable power delivery at specific times.

PSI Power Module Compatibility & Applications

PSI Power modules are engineered for a broad spectrum of diesel and turbocharged gasoline engines, including Cummins, Power Stroke, Duramax, Paccar MX-13, and Ford EcoBoost platforms, as well as agricultural mainstays from John Deere, Case IH, New Holland, and more. Installation is universally plug-and-play: harness connectors match factory wiring, avoiding any cutting or splicing. Ideal for light- and heavy-duty pickups, Class 7/8 semis, tractors, combines, and sprayers, these modules cater to everyone from long-haul truckers and rural farmers to commercial fleet operators seeking consistent performance improvements across multiple vehicles. The result is a versatile performance solution that fits seamlessly into the daily workflow of hard-working engines.

While it’s impossible to showcase every PSI Power module here, the examples below highlight key applications in agriculture, construction, semi-trucks, medium-duty, and light-duty trucks—complete with part numbers and the gains you might see in your vehicle.

Agriculture

PSI Power offers the JDCR2000 Performance Module as a Tier II–IV engine solution for John Deere engines from 2.9 L to 9.0 L. The three-position switch (Stock, +15%, +30%) allows the JDCR2000 Performance Module to provide up to 30% more horsepower and torque while achieving 10–20% fuel savings when operating in the field.

Construction

PSI Power Truck Edition

PSI Power’s Truck Edition serves as the company’s top-of-the-line performance module solution for trucks operating on highways and performing heavy hauling duties. Truck Edition modules connect to factory sensor lines instead of rewriting ECU code to optimize engine parameters including fuel injection timing and boost pressure while keeping everything within engine manufacturer safety boundaries. This method generates horsepower improvements between 30 to 70 hp and torque increases up to 141 lb-ft as well as fuel efficiency gains of 10 percent when compared to standard engine settings.

The 36200 Performance Module supports 2017–2023 Paccar MX-13 engines and the 35100 module supports 2017–2024 Volvo D11/D13/D16 and Mack MP7/MP8 engines to maximize their pulling capacity and throttle sensitivity under weight.

PSI Power Module Installation & Removal

The installation of a PSI Power module remains basic and non-invasive. You can install the module by connecting its connectors to the original factory harness without the need for cutting or splicing or programming modifications. The majority of installations require thirty minutes or less using basic hand tools. The process of removal starts with quick-release tab compression which enables unplug of the module and then restores the original connectors. The factory ECU stays untouched during the process so you can reverse the installation while maintaining your vehicle warranty. 

Safety, Emissions & Reliability

All PSI Power modules function as original engine components by respecting existing factory protection mechanisms rather than trying to replace them. The modules operate by adjusting signal patterns instead of modifying ECU programming which maintains all manufacturer-established exhaust gas temperature and turbo boost pressure and RPM limit parameters. These modules maintain all emissions systems in their original state because they leave DPF, SCR, EGR and their sensor systems intact thus allowing you to stay compliant with federal and state regulations. The company conducts extensive U.S.-based testing of each module through heat cycling and vibration testing and dyno runs to validate their durability in extreme operating conditions. PSI Power markets its products as “Safe & Reliable” while explicitly stating they integrate with factory settings to maintain both engine integrity and emissions compliance until the end of the module's life.
