Dodge Ram HD Diesel Truck Tuner Delete Kit
What Is a Dodge Ram HD Diesel Tuner Delete Kit Tuner delete Kit?
The Dodge Ram HD Diesel Tuner Delete Kit is a performance-focused solution designed specifically for Dodge RAM trucks running the 6.7L diesel engine. Unlike universal tuners, this delete kit by SPELAB integrates deeply with the engine’s ECM, providing precise control over emissions system removal—namely DEF, DPF, and EGR.
Key Functions:
-
Reprograms the ECU to disable emissions-related components
-
Supports DEF delete kit for Dodge Ram 6.7L Diesel
-
Includes optional CCV reroute features
-
Improves fuel efficiency and throttle response
-
Reduces regeneration cycles and system faults
This makes it especially valuable for owners of 2013–2018 Dodge Ram 2500 6.7L Diesel, who commonly experience high exhaust temps, cold-start hesitation, and repeated warning lights related to emissions.
Platform-Specific Design
As a specialized extension of the SPELAB Tuner Delete family, the Dodge Ram HD diesel truck delete kit is not a one-size-fits-all solution. It’s engineered around the unique operational logic of 2006–2021 Dodge RAM 5.9L / 6.7L diesel trucks, including:
-
ECM protocol compatibility
-
Torque and RPM limiter control
-
Optimized throttle mapping for towing and off-road conditions
Compatible Vehicles for Dodge Ram HD Diesel Truck Delete Tuner
When selecting a delete tuner for Dodge Ram 6.7L Diesel, compatibility is critical. The SPELAB Tuner Delete Kit is built to support a wide range of Dodge RAM diesel trucks from 2006 to 2021, with tuning strategies tailored to both the 5.9L and 6.7L engine platforms. For example, the 2006–2012 Dodge RAM 2500 5.9L Cummins may require different tuning files and bypass logic compared to the 2013–2018 Dodge Ram 6.7L Diesel models, which have more complex ECM encryption and updated emission sensors.
This kit is fully compatible with:
-
2007.5–2012 RAM 2500/3500 6.7L Diesel
-
2013–2018 RAM 2500/3500 6.7L Diesel (including Aisin & 68RFE transmission variants)
-
Select support for 2019–2021 RAM Diesel Truck with updated firmware and bypass cable
Understanding these year splits is essential. Earlier Dodge Ram 6.7L Diesel engines (pre-2012) tend to be more forgiving with tuning and require fewer harness mods. In contrast, 2013+ trucks often demand specific hardware setups like a Bypass Cable to successfully complete a DEF delete and avoid “Recovery Mode” issues.
Choosing the correct Dodge Ram 6.7L Diesel delete kit with tuner ensures smoother installation, fewer error codes, and complete access to tuning features like SOTF (Shift-On-The-Fly), power level switching, and throttle limiter adjustments.
Available Dodge Ram Diesel Truck Delete Kit Options and Functional Differences
SPELAB offers multiple versions of the Dodge Ram 6.7L Diesel delete kit with tuner to meet different performance goals and use cases. Whether you’re a commercial RAM owner focused on towing or a diesel enthusiast looking to unleash maximum power, there’s a delete package that fits your build. The two most popular configurations include:
Standard Kit: EGR + DPF + DEF Delete
This setup is ideal for most users. It removes three major emissions components and optimizes ECU tuning to improve fuel economy and reduce regen frequency. For example, owners of a 2014 Dodge Ram 2500 6.7L diesel truck often see gains of +60 to +80 HP post-install, along with complete elimination of DEF-related error codes and filter clogging.
Enhanced Kit: EGR + DPF + CCV + DEF Delete
This option adds a CCV (Crankcase Ventilation) reroute, which is especially useful in cold climates or heavy-duty applications. It's highly recommended for 2015–2018 RAM 3500 6.7L diesel truck models with Aisin transmissions, where the CCV system is prone to backpressure or condensation-related faults.
When it comes to tuners, SPELAB recommends:
-
Mini Maxx V1 – Best for 2007.5–2012 models, fast flash times, multi-channel data support, but limited compatibility with newer ECMs.
-
Mini Maxx V2 – Designed for 2013–2021 trucks, supports SOTF (Shift-On-The-Fly), live data displays, and better overall stability.
For drivers looking to change power levels on the fly—such as those using 2016 Ram 2500 6.7L diesel truck for both daily driving and towing—the Mini Maxx V2 combined with a full delete kit is the top-tier solution.
Performance Gains & Real-World Results from the Dodge Ram Diesel Delete Kit
Installing a Dodge Ram Diesel Truck delete tuner leads to immediate improvements in power output and engine responsiveness. Based on real-world data, a properly tuned Dodge Ram 6.7L Diesel delete kit with tuner can deliver gains of +60 to +100 horsepower and up to 180 lb-ft of additional torque—ideal for towing, off-roading, or heavy-duty work applications. For example, many 2017 Dodge Ram 2500 6.7L diesel truck owners report that after completing an EGR/DPF/DEF delete, regen cycles are eliminated, engine temps remain steady, and throttle response becomes noticeably smoother.
The DEF delete kit for Dodge Ram 6.7L Diesel also shows strong gains in fuel economy. On average, users report 3–6 MPG improvements, with some 2015 Ram 3500 6.7L diesel trucks running the Mini Maxx V2 tuner seeing up to a 7 MPG increase on highway drives. In long-haul or commercial use cases, this translates directly into lower fuel costs and improved operational efficiency.
Another key advantage is improved reliability in extreme environments. After completing a full CCV reroute, owners in colder climates no longer face warning lights from CCV freezing or pressure build-up. This is especially important for 2016–2018 6.7 Diesel-powered RAMs, where complete delete setups paired with SPELAB’s custom tuning files help eliminate recurring CELs and common DTC codes such as P051C, P259F, and P24DA.
Installation Best Practices & Common Mistakes for Dodge Ram Diesel Truck Delete Kits
While SPELAB’s Dodge Ram 6.7L Diesel tuner delete kits are designed for DIY-friendly installation, proper execution is crucial—especially on sensitive ECM-equipped models like the 2013–2018 Dodge RAM 2500/3500 diesel trucks. Most installation failures, recovery mode lockouts, or error codes result from skipped prep steps, unstable voltage, or firmware mismatches. Below are essential tips and common pitfalls to avoid:
Before You Start:
-
Disconnect the negative battery terminal to prevent power fluctuations during tuning.
-
Use a dedicated 10A+ constant current charger to maintain stable voltage during the flash process—low voltage is the #1 cause of failed ECU writes.
-
Only use SD cards formatted to FAT32 (4–8GB recommended) and loaded with firmware from SPELAB’s official update tool.
Common Installation Mistakes:
-
Bypass cable not installed (required for 2018+ RAM trucks) — will cause the tuner to freeze on the “turn key to run” prompt.
-
Interrupted power or cable unplugged during tuning — often triggers error codes #399 / #327 or “engine recovery mode.”
-
Incorrect vehicle selected in the menu — causes “unable to load” messages or soft-bricking of the ECU.
-
Trying to tune unsupported models (like RAM 4500 or early fleet-spec trucks) — results in error codes #294 / C747.
Pro Tips for a Smooth Install:
-
After install, do not start the truck immediately. Turn ignition off and wait 3–5 minutes before cycling power.
-
On first boot-up, go directly into “Diagnostics” and clear any DTCs.
-
Check if the truck is in Warm-Up Mode via Menu > Vehicle Setup > Defueling.
-
For the first 100 miles, run in Tow or No Power mode to allow the system to stabilize.
Using the delete tuner for Dodge Ram 6.7L Diesel with the correct method drastically reduces the risk of failed flashes, locked ECMs, or tuning modes not working—especially in cold-weather conditions or heavy-load operations.
FAQ
Q1: Do I need to keep the tuner plugged in after completing the delete?
A: No, once the tune is installed, you can unplug your Dodge Ram 6.7L Diesel delete tuner from the OBD port. The custom tuning stays stored in your ECU. However, without the tuner connected, the truck will default to "No Power" mode after a few drive cycles. The delete remains active, but power levels can't be switched.
Q2: Why is my Check Engine Light (CEL) still on after the delete?
A: Make sure all sensors for the EGR, DPF, DEF, and CCV systems are unplugged. Also verify that you're running the latest SPELAB firmware. Some codes—like P24DA or P051C—may require a specific tune file to fully suppress. Try clearing the codes after updating the firmware.
Q3: Is the bypass cable required for 2018+ RAM models?
A: Yes. All 2018+ Dodge RAM 6.7L Diesel trucks require a red-stripe Bypass Cable to communicate with the ECM. Without it, the tuner may freeze on “turn key to run” or trigger engine recovery mode.
Q4: Can I delete only the DEF system and keep the DPF or EGR?
A: Technically yes, but it's not recommended. The ECM logic expects all emissions systems to work together. Deleting just one may confuse the computer and lead to CELs or reduced performance. SPELAB advises deleting at least the DPF and DEF together for optimal results.
Q5: What's the difference between Mini Maxx V1 and V2?
A:
-
Mini Maxx V1 – Great for 2007.5–2012 models. Fast flash speeds, stable performance, but not compatible with newer ECMs.
-
Mini Maxx V2 – Designed for 2013–2021 trucks. Supports SOTF (Shift-On-The-Fly), real-time data, and updated firmware. It's the better choice for most users.
Q6: Can I adjust tire size and correct my speedometer with the tuner?
A: Yes, Mini Maxx V2 supports tire size and TPMS adjustments. However, note that some models may not support syncing changes to the RPM gauge. It's best to configure tire size changes before flashing the ECU.

Awesome product I put the 3" cutouts on my 78 nova and they work great. Easy to install.
After installing the Spelab intake my EGT’s have lowered about 150/200 degrees from stock! I tow 90% of the time with this truck, I should have done this upgrade way earlier!
This kit came in a very nice box with all the necessary hardware to complete the installation without any modifications. Installation time was about two hours working methodically by myself with some occasional help from my 13 year old son as he passed through the garage. As many others have commented it would be nice to have some printed instructions with the kit, but it is not hard to figure out. I went with the red version because it was the cheapest, and I think it looks great. After installation, custom tuning with a mm3 tuner, and an upgraded exhaust the 6.7 is opened up and free to run.
Great components solid workmanship very happy with the product and looks really rood. I went with the red
I am a mechanic so it’s hard for me to say someone with absolutely no skills that this is easy. But watch YouTube I will say everyone is worried about the egr exhaust bolts. But one video he sprayed them and soak them. I had sprayed mine each time I drove the truck and every morning for 4 days. Than another video a guy said drive the truck get it hot than when you go to take them out hit the socket and extension with hammer to loosen them. So I also did this. They all came out with absolutely no problem. I did have to take off my intake cause I did the ccv and disaster kit as well. And these bolts did not get sprayed. And one did break! I was able to get it out with wd40 and pb blaster and tapping with hammer. To drop dpf I sprayed the hangers with pb blaster used a pry bar and they pop right off. Remember when taking that off you might miss a coupe connectors so take your time! Also the back of dpf I had two broken studs and one so rusted that I had to use a grinder. After got it out I had to take a drill to my existing manifold cause the rusted bolts closed up the holes. Currently I left my dpf tank in the truck. I plan on removing it but I don’t have a reason yes!
Make sure to read all instructions and again take your time. I’m currently having issues updating the mini max cause I didn’t do it before install. But spe hands down was amazing the products everything was perfect besides the intake. The mass air flow sensor didn’t fit and to clean the metal shavings I used brake clean and it melted there spray paint on that one product, everything else i believe is powder coated. I know it’s not part of this kit but the cp4 disaster kit make sure you tighten hose clamps I did not do this and it cam off so I had to take upper and lower intake off on the side of the road and lucky the truck didn’t burn down. But I would say that was my fault for not verifying!
Fits great! Easy install! All parts come with this as well didn’t need to go out and get anything. Not only that but the price man that’s damn good
Good fitment on all items. All block off plates fit good and dont leak. Downpipe fits perfectly. All gaskets included good quality.
I’m so happy with my egr delete kit and intake. I made the best decision in choosing Spelab to enhance my 2500 ram truck. I’ll keep buying more stuff from them. It’s starting to be an addiction!! Thanks Spelab!!
The exhaust and muffler fit great. Had to make one cut but that took no more than a couple minutes to measure and make the cut. I’m very pleased with the muffler included, sounds good but keeps the noise down and no drone in the cab. Will buy again.
Everything fit great. The finish is good and it includes everything you need to get rid of that POs Egr cooler
You know how it goes when you try to save a dollar, you cut cost of quality. But this is actually not the case so far. Finish is smooth, no bad cuts that i could see. Plate wasn’t warped with was a concern for me but no leaks this far. I’d buy again
Love the pipe however one band clamp was damaged upon arrival. I was able to bend it back to the correct form and use it. All hangers were in the correct location took about 30 mins for me to install by myself.
Intake came in nice and shiny looks like a great product also got the red intake plate and man oh man does it look sharp, overall I recommend Spelab products. Looks clean performs even better
Comes quickly in a little box. I work on my truck but am no mechanic. It took me 2 hours to remove and install the kit. Im very happy with the outcome. Im going to give it 5 starts but you do have to reuse the two gaskets on the EGR cooler. My advice is pick them up from the parts store so its all new. Total cost is $24 for both. They should be included but im still very happy.
Great product. Does everything it is supposed to do. I do wish it came with printed instructions. Following along with greasy fingers on my phone was problematic. Also, the hose fitting for the coolant line was a size too small. I had to purchase the correct size.
