What Is a Duramax Tuner Delete Kit?
A Duramax tuner delete kit reprograms your GM 6.6L diesel's ECU to bypass restrictive DPF, EGR, and DEF systems, unlocking smoother power delivery and efficiency.
Our 6.6 Duramax tuner, like the Mini Maxx series, is tailored for LMM, LML, and L5P platforms—perfect for a 2011 Duramax tuner or 2022 Duramax tuner setup.
No more limp mode or costly DEF refills; just pure, reliable performance tested by our experts.
Why Tune a Duramax? Key Benefits
Tuning transforms your truck: Expect 20-50% HP and torque surges for towing beasts, plus 3-5 MPG savings on economy tunes. Fix turbo lag, enhance low-end pull, and extend engine life by ditching clogs and overwork.
Most DPF/EGR deletes need tuning to avoid limp mode—our L5P delete tuner ensures seamless integration. Whether daily driving or hauling, enjoy custom modes for every scenario, backed by rigorous quality checks for peace of mind.
Components Included in a Duramax Tuner Delete Kit
Each kit packs essentials: Handheld tuner (e.g., Mini Maxx V2 for LML), bypass cables, SD cards with pre-loaded files, and hardware for EGR/DPF reroutes.
Add-ons like our LM2 Duramax delete kit cover sensors and filters. Everything's plug-and-play via OBD, with 10+ years of expert design for easy installs—no special tools needed.
Duramax Tuner Buyer’s Guide
Match your ride: L5P (2017-2025) demands TCM unlocks for secure tuning, unlike LML (2011-2016), which thrives on flash devices.
For EGR/DPF delete tuning, choose tuners supporting full deletes like our Duramax DPF delete tuner. Canned tunes suit quick wins; custom like PPEI for pros.
Budget-friendly? Our tuners for Duramax start low, delivering high ROI through fuel savings and durability.

Keeps my truck in v8, Great!

EGR Delete Plug Kit for 2010-2024 Cummins ISX 15 CM2250 CM2350 Plug Kit

Nice!

Stops the motor from kicking down to 6 or 4 cylinders which is supposed to add years to the motor. Thanks

Even before I purchased this, I was experiencing minor hesitation issues without the Check Engine Light. Also since I purchased this truck 4 yrs back, as I type this out, I had to replace the EGR within 3 months. Other vehicles owned with EGR have not experienced this level of issue when the code was checked on the CEL. Now I have been living with the EGR issue in recent months this time, until I determined what steps I wanted to take to permanently resolve this. After weeks of searching, and no real difference between everyone I looked at on the web, and it kinda was a no brainer, spend the money on a new EGR valve, or spend the same amount and eliminate, in essence bypass the valve emission system all together, especially since this truck at 35 years is not required emissions check in this state at 25 years.
My apologies for taking this much time to respond. The block off plate in this kit for my truck is not necessary. The plug on the sensor was removed, the slave was set, the wiring harness secured to a location out of the way of any issue, CEL cleared. After 3 days with some minor hesitation issues still existing, it was determined the vacuum line originally left alone might need to be plugged. To conclude since the vacuum line was plugged there were no signs of hesitation from standing start or any driving conditions requiring further increased pressure on the gas.
Thank you I am pleased with the response, the resolution of the EGR issue, full stop...

I bought the kit with the up-pipe to delete the EGR cooler feed inlet from the exhaust instead of the small disk that blocks it off. My mistake but, don’t get pinched like I did.

I run a small business, and it ain't always easy. Sometimes the best you can do is correct mistakes when they happen. I had a problem with the two AFM disablers I purchased (purchased together).
I contacted EGR and they acknowledged they did have an issue with some of them. They immediately sent me two replacements and the replacements are working fine.
In my opinion, that's how it should be. Thanks.

Parts were excellent quality, shipping was super fast. Everything installed very easily and I already noticed a difference in the engine performance.
