Moreover, suppose you're looking for a tuner that will allow you to delete all of your emission components while ensuring you don't have any check engine lights or DTCs (diagnostic trouble codes). In that case, the Mini Maxx is the tuner for you.

In addition, we recommend one of our custom-tune tuners for those looking for more power. Please reach out to our sales team for more information.

Performance Mini Maxx Race Tuner and Fuel Economy

Additionally, the Mini Maxx is a great option for those drivers looking to save on fuel. Most truck owners who have installed the Mini Maxx have reported a substantial increase in mpg (sometimes up to 5 miles per gallon) when paired with the correct DPF delete pipe and EGR block-off kit.

Importantly, installing the Mini Maxx is simple and is among the fastest ways to remove all the emissions systems. People using the Mini Maxx never look back.

Is it legal to have a Mini Maxx Tuner installed in your truck? What about the emissions?

Please note that the Mini Maxx race tunes are designed for off-road use only.

Similarly, if you live in a country without such requirements, the Mini Maxx is a great option for tuning your truck cheaply.

What does a Mini Maxx Tuner do?

The Mini Maxx tuner is a device used to improve diesel engine performance. It does this by increasing the power and torque of the engine, as well as improving the fuel economy. The Mini Maxx tuner is available for GM trucks. It can be installed in just a few minutes and is easy to use.

By installing this state-of-the-art DPF delete race tuner you will be able to delete the following emission systems:

DPF: Diesel Particulate Filter

Easily delete the components of your DPF system. The Mini Maxx allows you to remove all the components of your truck's DPF system while turning off all the codes for the related sensors, eliminating any check engine lights.

EGR: Exhaust Gas Re-circulation

The Mini Maxx V2 delete tuner disables the EGR function and any related check engine lights and DTCs.

It will work if you leave the EGR system installed (run with the EGR system) and it will also work if you install an EGR block kit. Works in conjunction with an EGR block.

No more leaks from the EGR system! Yes say goodbye to coolant leaks from the EGR!

DEF: Diesel Exhaust Fluid

This tuner will allow you to turn your urea injection system off completely, which will allow you to remove the tank and all related sensors. This is a great option for those that want to remove the extra weight from their vehicle or those that are having problems with the system.

Note: With the Mini Maxx, ULSD (Ultra-Low Sulfur Diesel) becomes optional. It opens up the possibility to use high-sulfur diesel fuels.

The Mini Maxx is the key to transforming your truck into a more capable, economical powerhouse.

  • Delete tuner
  • OBD Connection box
  • HDMI Cable connecting the box to the tuner
  • Power adapter
  • Micro SD to USB Adapter
  • Fuse tap
  • Mini Maxx Tuner Mount

I wood give them 5 Stars on my order. I'am very please with my exhaust system. Thanks

Robert

Brum

I'm really happy with the Ecodiesel delete kit, which comes with an ECM and transmission tune.,My first impressions are really positive.,I installed this kit last weekend and the results have been outstanding in terms of power and fuel efficiency.,My 2016 3.0L Ecodiesel was in bad shape, stuck in 'limp mode' due to an electronic throttle fault and a DPF that was completely full.,The dealer wanted to charge me over $3,000 to replace the DPF filter, but I decided to do the installation myself.,While it was a tough process, it was definitely worth the effort.,After completing the hardware installation, I cleared the engine codes and downloaded the ECM/transmission tunes.,I went for the 40hp tune, and I can really feel the difference - there's better throttle response and a 2mpg improvement on rural roads so far.,We'll have to wait and see about the long-term durability, but I'll definitely update if I run into any issues.,Overall, I'm really pleased with the product, the instructions, and the customer support.

John, I'm a big thumbs up on your team overall. Very pleased with the level of support prior to, during, and after the changes I made. The number one differentiator between your team and others is the ability to pretty quickly get a live person on the phone and if needed for them to remote into the laptop connected to the vehicle. There were a few issues, but quickly addressed and or your guys confirmed for me what was happening and that all was well and as expected. Good work by all! A+ so far! Thanks Chris

Jeremy

White

Packages arrived and in good shape. When I had any questions someone would follow up with an answer. My RaceMe Ultra was easy to install and had no problem with the EGR delete kit. I did have a problem with my pipes due to the bend in the pipe that replaces the muffler. Only 2 ways I could put it. The bend up or down would not let me hook up my hanger mounts for support.

Jeff

Watkins

I am more than happy with it. I have completed the DPF removal and straight pipen install. I have not removed the EGR. I can say that I have picked up more power and 3 more mpg towing. I have an 8k pound bumer pull camper. There is a little black smoke when I punch it; none if I drive "normal". My wife said it is louder, who asked her. I have been on the fence but your price and the extra $100 off, with free shipping was the factor. Thanks for the entire process from ordering to installation videos.

Scott

Definitely worth it THANK YOU DIESELLION.COM for everything I will be sending business your way with all my friends

EGR kid was a breeze, for me at least. Everything I needed was in the kit. Only thing I want to say to help for future kits, is that the gasket for the intake neck/tube, it was bent and on the verge of tearing. I was able to reuse the original one on my truck since it is a very low mileage truck. Otherwise, thank you and hope I can find something on your website I can use!

Anthony

Bran

Awesome! Install wasn't too bad on 2017 Ecodiesel Ram 1500. Truck is much more responsive and should last longer now that I am no longer spewing carbon into my intake manifold.

Baros

Everything went well. Took me 4 hours to complete, solo. Only gripe I could have (which I don't) would be the lack of instructions for the bracket that bolts to the exhaust. Took me a while to figure that out as the instructions showed a different set up. Preciate the kit. Have recommended to other folks.

Joe

Murphy

5 stars Fast shipping, quick response to my email, excellent products. Tune loaded quickly with no issues and shifting is smooth with the tow tune but I'm still experimenting. I needed a exhaust that wasn't to noisy and yours a worked perfectly and no leaks from the clamps. I did remove the 4 inches from section of straight pipe to fit my long bed crew cab but that seems to be the norm so the same pipe will fit the long bed mega cab. You were a word of mouth recommendation and I'm glad I remembered the name of your company. Thank you for helping me bring my truck back to life.

Kit was great so far 5" was very tight at the down pipe had to bend it on frame side. And had to weld up the clamps that hold exhaust together they were a little chincy other than that no complaints at all.

Truck is back to running like it should thanks

Johnny

Quarles

Product was not really compatible with the C/C as turbo is smaller so GDP will only give me 1 tune. I understand why but, I bought the 5 position switch was so I could adjust power as at times I do not tow and others 30k lbs. Other than that like the tune and GDP tech line was very, very helpful So can't use the 5 position switch but will keep until I install a larger turbo as per GDP. Thanks for the product and it really sounds like a truck now.

Bill

Hats off to diesel lion. I purchased my 6.7 ford tuner approximately three weeks ago I received my tuner within three days of ordering, which was fantastic. Wasn’t expecting it for a week to a week and a half. when I received it, I opened up the box to see what came with it and noticed the gauge wasn’t in the box was planning to put it on the upcoming weekend was very disappointed at the time. I thought I was gonna have a heck of a time trying to get a hold of them and resolve the issue I first called them no answer then email them got an answer with an hour after hours. I sent them photos of what I received in the box and the person that have been talking to said he would send me one out, I thought well it’ll be another week or two before I received it. I got it within two days again very very happy with their response and concern they sent me a whole new unit very appreciative to diesel lion the way they handled it very very happy with them. Long story short if you need to order tuners or anything and need good service order from diesel lion they will take care of you. Thank you again diesel lion. If there’s anything else I need I will definitely order through them. Thanks again Cardel Howell.
