I had another Tuner, Edge Evolution CS2, but the Minimaxx V1 works sooo much better! I have 2009 F350 6.4 Diesel. My truck runs PERFECT now and it has much MORE POWER! Love it!

Overview
The GM Duramax 6.6L LML delete kit is engineered for 2011-2016 trucks that see real work, towing, and sustained load. This complete LML delete kit replaces the restrictive factory emissions hardware with a 4-inch DPF-delete race pipe, full EGR valve and cooler delete system and a pre-configured Mini Maxx tuner built specifically for deleted LML applications. By reducing backpressure and excess exhaust heat, this LML delete kit is designed to lower EGTs, improve turbo response and deliver more stable power and drivability when properly installed and calibrated.

Important Variant Selection Notice
This LML delete kit is offered in two variants based on factory turbo outlet flange design. Selecting the correct version is mandatory for proper fitment:
- 2011-Early 2015 - Uses a V-band clamp at the turbo outlet.
- Late 2015-2016 - Uses a 3-bolt turbo outlet flange.
Due to production overlap, VIN decoding may be inaccurate. Flange type must be confirmed by visual inspection at the turbo outlet before ordering.
Key Features & Build Details
- 4' Stainless Steel DPF-Delete Race Pipe - Mandrel-bent construction minimizes exhaust restriction and heat retention compared to the factory emissions-equipped exhaust.
- Complete EGR Valve & Cooler Delete System - Includes precision-machined block-off plates and reinforced silicone coolant bypass hose to fully remove failure-prone EGR components.
- Flange-Specific Exhaust Design - Available in V-band or 3-bolt configurations to match production-year turbo outlet connections.
- Mini Maxx Tuner Included - Supplied with off-road performance calibrations designed specifically for deleted LML applications.
- Full Hardware & Gasket Kit - All required fasteners, clamps, and sealing components included for a complete installation.
Performance Benefits
- Reduced Exhaust Gas Temperatures - Improved exhaust flow lowers EGTs during towing and sustained load conditions.
- Improved Turbo Response - Lower backpressure supports quicker turbo spool and stronger mid-range torque.
- Enhanced Power Potential - Optimized airflow provides a solid foundation for performance-oriented tuning.
- Lower Thermal Stress - Eliminates soot accumulation and heat buildup associated with factory emissions systems.
- Calibration-Driven Efficiency - Fuel and timing strategies are optimized through included tuning.
Installation Notes
Installation is rated as moderate difficulty and professional installation is recommended. The vehicle must be tuned using the included Mini Maxx device before removing any emissions hardware to prevent diagnostic issues. Factory exhaust removal may require cutting, and flange type must be visually verified at the turbo outlet prior to ordering.
Frequently Asked Questions
How do I identify whether my truck uses a V-band or 3-bolt flange?
Inspect the downpipe connection at the turbocharger. A circular clamp indicates a V-band flange, while a triangular flange with three fasteners indicates a 3-bolt configuration.
Does this kit fit Cab and Chassis trucks?
No. Cab and Chassis models use different exhaust routing and mounting locations and are not compatible.
What is the difference between 2015 and 2015.5 LML trucks?
2015 is a split production year. Early-2015 trucks use a V-band flange, while 2015.5-2016 trucks use a 3-bolt flange. Because of production overlap, visual inspection is required.
Can I add a muffler to this system?
Yes. A 4-inch inlet/outlet muffler can be installed for sound control without affecting tuning requirements.
Is this Duramax LML EGR Delete Kit?
This isn't just a standard Duramax LML EGR delete kit; it is an all-inclusive performance package that includes:
- Tuner
- Preloaded LML tuning
- EGR delete components
- Required pipes
If you are only looking for 6.6L Duramax LML EGR delete parts (such as EGR block-off plates for an EGR-only delete), those items are sold separately.

Customer Reviews
Overall rating: 4.7 / 5 from 232 reviews.
The screen shows alot of details including engine code eliminates the need for a separate code reader. The on the fly tuning provides high horsepower within seconds if needed as well as higher fuel economy to going from 10-14mpg to 16-20mpg. The only downside to this whole kit is the mounting of the tuner itself. There's a windscreen suction cup that come with it but I wish they gave an option for a more sleek design like the one I had to buy though a 3rd party.
Quality products with awesome prices .
Good quality, quick to install.
It’s rlly good deleted my truck in secands
Night and day difference, I had Spartan N Dash before I bought this H&S.
It is definitely worth it. Truck runs better with no worries of DEF heater leaving me stranded. Put about 6000 miles on it no problems.
Super easy install. Best price online. Cleared my dpf codes no problem. The power increase is very impressive. Tuner was shipped quickly.
Purchased the system for my 2017 F350, mainly because a buddy said I would get better fuel mileage! While that is the furthest from the truth, I relish in the increased power and loud exhaust to scare the slow people who don’t know what a speed limit is. I purchased 36.5 tires for my truck and liked that the Mini Max V2 was able to calibrate for the larger tires and lower tire pressure requirements. Over all, quite pleased.
Plug and play super easy! Added this tuner along with their Egr and dpf delete. Amazing sound and power levels. No professional help needed.
I am not a certified mechanic and the Mini Maxx was simple to install and very easy to tune and delete my 2009 Dodge 3500 6.7 Cummins Diesel. I have increased my performance on horsepower and mileage on both the performance setting and the tow setting. I am very impressed with this product and recommend it as well.
Probably was the Best Decision I’ve made! Let me tell you , This mini Maxx did things for my truck that thousands and thousands of dollars can’t do! I highly recommend this unit for any GMC Duramax owners especially to get ride of all the check engine issues related to the emissions system. Worked perfectly for me .
Tuner works great, i do have a couple questions for someone if they could get ahold of me though! Would be greatly appreciated.
Still playing with it. Don't like there is no manual. Have to go screen by screen. When first installed I thought something was wrong because where the power levels are shown it said No Power. I thought it was the tuner or my truck. It ended up being one of the power levels. All in all easy to install and placed my unit down by my right knee at the little pocket there. Still easy to access and not visible from the outside.It did clear up all my problems so far. Waiting to pull my trailer so see the difference.
Works exactly as advertised. 👍🏻
Truck runs fine but factory exhaust brake doesn't work with tuner but works fine without. Unable to download old version of tuner onto SD card and tuner depot tech doesnt have any spare cards to program so stuck without exhaust brake function at this point.
The tuner really woke the truck up. It’s a big difference like night and day. And especially the delete with 4” Exhaust. Truck sounds like a jet ready to take off now. Great purchase
Everything was as expected works perfectly the install was pretty easy and didnt take long at all
Great product! I chose the standard tune for my 2016 6.7 powerstroke. It went in easily and now I have no more check engine light for faulty DEF components. What I like about this tuner is it does not need to be left plugged in to the OBD port. I just want my truck to run as it should at the factory settings and this product seems to have done the trick.
product specified that it would work on my 2014 ram 5500 cab and chassis. installed it and immediatly had a urea code. tried to call tuner depot but was told i need to email them with my issue. after emailing i got a response that it wasnt the tuner but the truck with the problem. brought the truck to a diesel shop, had them install a CORECT tune file with no issues. do not recommend this product. a complete waste of $900!!!!!
Wow woke up my super duty
TUNER DEPOT IS AMAZING!!
Fuel mileage pickup around 2 mpg in town. Work's great haven't pulled anything yet but think it'll be ok. Let problem get it the first one got lost gave customer service a call and they sent me another one right out had it in 3 days . That was great customer service!
Works great. Downloaded perfectly. Does as expected. I personally was not looking for performance, I had a display that was to reduce speed in 45ish miles. Installed in a off road toy truck and didn’t need speed reduced Worked exactly as I needed
N/A
Worked great with no issues.
Didn’t work correctly with original card or with replacemen card. My truck is sitting in my shop for 3 weeks now with no fix! Have been waiting on return envelope for 5 days
More power now it get up and go.
Great product, gas saving and more power.. thx
Plug and play as described. I too have a V1 in another truck, the V2 was an easier install and download.
Great
Very helpful throughout the whole process!
works great and was easy to install
Everything went together, just had to search up YouTube videos how to program
It was super easy to install. It works great.
Easy installation love the extra benefits it gives as well just curious why I’m getting a p2457 code now
EVERY THING WORKS GREAT, EASY INSTALLATION AND GREAT HELP WHENEVER AN ISSUE ARISES. PURCHASED MULTIPLE ITEMS FOR MULTIPLE TRUCKS AND WILL CONTINUE TO USE THEM FOR FUTURE PURCHASES.
Works great as always
Excellent product 💯
