For diesel truck owners who demand maximum performance, SPELAB Diesel Tuning isn’t just an upgrade—it’s a precise release of mechanical potential.
Whether you're driving a 2020 RAM 2500 6.7L Cummins, a 2015 Chevy Silverado 2500HD 6.6L Duramax, or the legendary 2003 Ford F-250 7.3L Powerstroke, SPELAB’s diesel tuning solutions deliver noticeable improvements in torque, throttle response, and fuel efficiency. By recalibrating factory ECU parameters and replacing restrictive OEM components, these tuning systems enable your diesel engine to run stronger, cleaner, and more efficiently.
SPELAB Diesel Tuning includes a complete range of performance parts—from ECU tuners and EGR delete kits to DPF delete pipes and CCV reroutes—each engineered to meet the rigorous demands of towing, off-roading, and heavy-duty applications. Whether you're hauling a trailer, navigating uneven terrain, or running a daily workhorse, SPELAB ensures your engine delivers reliable performance under pressure.
These upgrades are ideal not just for enthusiasts but also for professionals who use their diesel trucks for farming, construction, or long-distance hauling. With SPELAB, you’re not just enhancing horsepower—you’re improving control, efficiency, and long-term engine durability.
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.

Each SPELAB component is carefully engineered to replace factory bottlenecks and deliver a well-balanced system upgrade. Whether it’s your 2016 RAM 2500 6.7L Cummins or 2015 Ford F-350 6.7L Powerstroke, this transformation isn’t just about more power— it’s about smarter, safer, and cleaner performance.
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. For trucks like the 2015 Ford F-250 6.7L Powerstroke or the 2008 Ford F-350 6.4L Powerstroke, SPELAB tuning focuses on recalibrating delicate timing windows and fuel delivery strategies while improving turbo response and reducing system strain.
SPELAB recommends combining the Tuner, EGR Delete, and DPF Delete for a full transformation, especially on 6.0L and 6.4L models which are notorious for EGR and coolant-related issues. These changes not only restore power but also improve reliability—critical for towing and off-road use.
Cummins Tuning: Unleashing Raw Power with Simplicity
Cummins engines, such as the 5.9L and 6.7L, are celebrated for their mechanical simplicity and bulletproof construction. Tuning a 2016 RAM 2500 6.7L Cummins or a 2007 Dodge Ram 2500 5.9L Cummins often yields dramatic gains because the engine is highly responsive to fuel and boost recalibration.
SPELAB tuning on Cummins platforms typically starts with a DPF Delete Pipe and a Tuner for immediate power and throttle gains. To maintain safe EGTs during heavy hauling, an EGT Relocation Kit is highly recommended. Cummins owners often favor this platform for race-ready builds and long-distance towing rigs.
Duramax Tuning: Navigating Electronic Complexity
Duramax engines like the LML 6.6L and L5P 6.6L offer a strong foundation but come with tightly integrated emissions and ECU systems. Trucks like the 2014 Chevy Silverado 2500HD 6.6L Duramax require tuning that carefully navigates factory limits without triggering limp modes or DTCs.
SPELAB recommends starting with a CCV Reroute to protect the turbo from oil vapor contamination, followed by Tuner and DPF Delete modifications. The CAN BUS Plug is especially useful for Duramax users looking to monitor tuning effects in real time and ensure system health.
Whether you own a 2020 RAM 2500 6.7L Cummins, a 2018 Ford F-350 6.7L Powerstroke, or a 2015 Chevy Silverado 2500HD 6.6L Duramax, SPELAB delivers tailored tuning solutions that respect the unique DNA of your engine while pushing it to peak performance.

All parts arrived promptly and packed well. Installation was smooth and trouble free except for the tube style heater which would not thread into the new intake elbow. The provided plug threaded in fine so will have to revisit that issue before winter.

Overall I was very impressed. Pricing was great, everything I needed was provided. Quality of the parts was good. I would definitely recommend this package when compared to others.

Great products! Works perfectly!
Thank you so much!!

No written instructions came with the kit, no big deal. You will definately need the IAT extension wiring harness, which we wasnt told we needed. I ended up making my own extension but if you don't the truck will not start. Also the intake horn doesn't fit straight onto the inlet tube so if it looks crooked just make sure the clamp is tightened.

Packaging was good, install was simple, and it sounds great. What more could you ask for?

Kit went on fantastic, all hangers lined up. Freed up power and MPG. I installed the SPELAB muffler too, good combo, good sound. It drones under load and at about 70 but not unbearable. Super happy.

Have purchased a few different things , all worked at advertised! Will be making future purchases.

Great finish, not a terrible install, just time consuming. Just take your time it, we’ll worth it!

I took my F 150 to a local mechanic to get the differential cover and gasket removed, the fluid drained and then everything put back together. I didn't want to bother. My mistake. I got the truck back, put a piece of cardboard under the rear differential and determined that it was leaking slowly. I went back to the mechanic, they supposedly fixed it, but the cardboard check failed again. I went back to the mechanic and they told me it was the pinion seal bearing that was leaking. This problem never existed until I had taken the truck to them. I got the truck back in the pinion seal was no longer leaking but I still had a slow leak from the gasket around the differential cover. $400 later in three trips back to the mechanic I gave up, bought the SPELAB cast aluminum cover and the lube locker gasket plus the necessary fluid and did it myself. No leaks since then. I particularly like the little sight glass since I was able to get the fluid exactly to the halfway mark within the sight glass. I should never have gone to the local mechanic in the first place.

Very well made with quality materials and hardware! You will not be disappointed.

SPE ccv reroute is the best bang for your buck and works very well. Easy install and looks great when installed.

This 5” downpipe back kit fit absolutely perfect. Could not ask for a better fit and finish of this kit. All the hangers are in the correct location and the clamps supplied are of quality!

Installation was a breeze!

I bought this kit for my 2019 Ford F350, the same kit I bought for my 2014 F250 almost 5 years ago. The first kit I had significantly boosted my power to pull my 5th wheel up I-17.
While I haven’t pulled anything big yet with my F350 I can already feel the difference in power and performance.
VERY happy with my purchase and…no more DEF (garbage!).

Great replacement cover! Looks great and was easy to install and makes it much easier and cleaner to change my differential gear oil!
