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

Everything in the kit ordered worked great! I am a happy customer and will likely purchase again!! Thanks for the great products. Thank you for your time.

Tony

Russ

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

King

Very satisfied with the results of the Tow Haul tune, good service and fast shipping. I do however like talking to someone on the phone more than communication thru email. (I'm just a little old school I guess)

Mike

Moyers

Absolutely amazing customer service and shipping. Have told several people to do business with you. Couldn't be happier. 5 stars all the way

Philip

Triplett

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.

Kenneth

Polley

A PLUS. Everything was perfect. Tunes work as they should. Drivability is better than factory programming. Very happy and will buy from again.

Ian

Lewis

Great kit. Truck runs great. I went from 16.2 highway mpg to 19.9 highway mpg. The kit did not substantially increase exhaust noise, the truck is still quiet for a diesel. I am very pleased. I can now go down to grand isle fishing and not have to worry about my truck saying in 50miles your truck will only go 50 mpg. What a relief!

Chris

Paul

The kit works great. The DPF and DEF deletion pipes fit perfectly. The EGR Kit had everything I needed and the RaceME Ultra was easy to install. The way the truck runs now is awesome, The horsepower and fuel mileage was exactly what I was looking for. The fuel mileage on my 2017 Dodge with the 6.7 cummins with from 15-16 MPG to 24-26 MPG on the highway and from 11-12 to 18-19 in town. I'm extremely happy with my purchase. Thank you.

Dave

Peevey

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

Great kit, very satisfied with the quality and performance and your customer support is fantastic, thanks for making the 6.7 run and sound great

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.

Brett

Nichols

Very happy with my order. Could have used some instructions on the install. Thanks Youtube. Also don't really understand the trans tune. Didn't get any verification it was installed on the tuner or even how it is installed. Don't even know if I really have it.

Tracy

Funderb

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

Stribling

thanks again the truck runs great went from 27 to 32 mpg

James

Milburn

I am stoked! Thank you ALL for being a part of the solution. It burns me up to know the amount of great engines out there being ruined by the ridiculous laws and science being forced on great Diesel engines. No doubt about it, there are less than a handful of un-needed factories blowing more pollution into the world than ALL of the diesel engines combined. Thank you again for all you do! God speed.

Mike

Thompson

This product is really great. It has significantly improved the fuel mileage, going from 23 mpg to 28 mpg. On top of that, the engine now responds much more quickly when taking off.

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.

Daniel

Johnson

Everything I needed was in the kit I was very happy with Everything except the shift on the fly selector. I spent 2 hours installing it in a very inconspicuous location. After I installed it we could not get the proper voltage reading for it to work correctly with my truck. So now I have it still mounted in my truck but I had to unhook it so it was a $150 item that I won't be able to use. But everything else worked very well and I am pleased with the outcome of the installation. Thank you for your products. Will be purchasing more form your company in the future

Bobby

Everything was great my order was exactly what I wanted no hassle no problem. Would definitely order again from Y'all again.
