What Does SPELAB Diesel Tuning?

While OEM (Original Equipment Manufacturer) setups are built for mass-market reliability and emissions compliance, they often limit a diesel engine’s full potential. SPELAB Diesel Tuning unlocks this potential by modifying and replacing key factory components that restrict performance.

For example, stock ECUs in trucks like the 2019 Ford F-250 6.7L Powerstroke or 2016 RAM 3500 6.7L Cummins come programmed with conservative fuel and timing maps designed to prioritize emissions over output. SPELAB’s ECU tuner recalibrates these parameters to deliver more aggressive and efficient combustion. Similarly, factory-installed EGR (Exhaust Gas Recirculation) and DPF (Diesel Particulate Filter) systems are designed to reduce emissions but often cause carbon buildup and increased exhaust backpressure. SPELAB’s EGR delete kits and DPF delete pipes remove these restrictions, helping engines breathe easier and run cooler.

For engines like the 2014 Chevy Silverado 2500HD 6.6L Duramax, replacing the OEM CCV system with a rerouted design prevents oil vapor from re-entering the intake—significantly improving system cleanliness and turbocharger longevity. The result across all models is a smoother-running engine with increased power, better throttle response, and fewer long-term maintenance issues.

SPELAB Diesel Tuning Components and Functions: Building a High-Performance Diesel System

SPELAB Diesel Tuning isn’t just one product—it’s a complete diesel performance ecosystem. Each component plays a critical role in transforming your diesel truck from factory-limited to fully optimized. Whether you're driving a 2018 RAM 2500 6.7L Cummins or a 2012 Ford F-350 6.7L Powerstroke, SPELAB offers precise, vehicle-specific upgrades that maximize power, efficiency, and control.

1. Tuner (ECU Programmer)

The tuner is the brain of SPELAB Diesel Tuning. It recalibrates your truck’s ECU to adjust fuel delivery, air intake, ignition timing, and turbo boost logic. For models like the 2019 Ford F-250 6.7L Powerstroke and 2017 RAM 2500 6.7L Cummins, the SPELAB Tuner offers multiple power levels—Daily, Towing, and Performance—switchable on demand.

Users can expect up to a 15–30% increase in horsepower, faster turbo spool times (up to 40% improvement), and reduced fuel consumption—all while staying within safe engine parameters. It's ideal for heavy-duty tasks or high-performance builds.

2. EGR Delete Kit

The EGR system recirculates exhaust gases to reduce NOx emissions, but it also introduces carbon buildup and reduces combustion efficiency. SPELAB’s EGR delete kits use high-temperature, corrosion-resistant hardware to completely remove the EGR system.

Perfect for trucks like the 2014 Chevy Silverado 2500HD 6.6L Duramax or 2015 Ford F-350 6.7L Powerstroke, deleting EGR can lower engine temps by 10–20°F, reduce soot buildup, and extend engine life—especially in demanding use cases.

3. DPF Delete Pipe

While DPF filters help with emissions, they restrict exhaust flow and cause high backpressure, especially under load. Trucks like the 2016 RAM 3500 6.7L Cummins can suffer from performance loss and regeneration issues due to clogged filters.

SPELAB’s DPF delete pipe features a straight-through, stainless-steel design that drastically reduces exhaust restriction. This results in cooler exhaust temps (up to 150°F lower) and as much as 35% faster engine response.

4. CCV Reroute Kit

OEM crankcase ventilation systems reroute oily vapors back into the intake, leading to dirty intercoolers, intake valves, and turbochargers. SPELAB’s CCV reroute system vents these vapors externally using a sealed, single-direction design.

It’s a must-have for trucks like the 2013 Chevy Silverado 2500 6.6L Duramax or 2011 Ford Super Duty 6.7L Powerstroke. Benefits include cleaner intakes, improved turbo longevity, and better combustion efficiency.

5. EGT Relocation Kit

After tuning, accurate exhaust gas temperature (EGT) readings become critical. OEM sensors are often located too far downstream for timely readings. SPELAB’s relocation kit moves the sensor closer to the turbo for real-time monitoring.

Ideal for vehicles like the 2018 RAM 2500 6.7L Cummins or 2020 Ford F-350 6.7L Powerstroke, this upgrade reduces temp reading lag and ensures safer tuning conditions, with temperature accuracy improved by ~15°F.

6. CAN BUS Plug

The CAN BUS Plug allows users to monitor real-time ECU data, engine vitals, fuel economy, and fault codes—without disassembly. It’s plug-and-play via the OBD-II port and essential for making the most of your SPELAB tuning setup.

On trucks like the 2021 RAM 2500 6.7L Cummins or 2019 Ford Super Duty 6.7L Powerstroke, this tool gives you fast insights to adjust, fine-tune, and monitor everything from boost levels to regen cycles.

7. Delete Kits (Full System Packages)

For customers looking for a one-and-done solution, SPELAB offers full delete kits that bundle EGR, DPF, and DEF deletes with all necessary hardware and tuning files. These are especially helpful for platforms like the 2016 Chevy Silverado 6.6L Duramax LML, where system complexity demands complete integration.

With full delete kits, users typically see a 30%+ horsepower gain, reduced fault codes, and greater system synergy—all with installation-friendly compatibility.

Tuning Differences Between Powerstroke, Cummins, and Duramax Diesel Engines

Not all diesel engines respond to tuning in the same way. That’s why SPELAB Diesel Tuning offers platform-specific solutions designed to match the engineering traits of Powerstroke, Cummins, and Duramax engines. Understanding these differences is essential for achieving optimal performance gains.

Powerstroke Tuning: Precision for Complex Systems

Ford’s Powerstroke engines, especially the 6.0L, 6.4L, and 6.7L variants, are known for their complex emissions systems and tight ECU control.
