✅ Industry Leading DPF/EGR/DEF Delete Tuner

✅ Bullet-proof Engine Reliability

✅ Massive Fuel Savings

✅ Simple Plug & Play Tune Installation

When you install the delete tune, your truck will no longer have emission related codes or warnings. 

This includes all

1) “See Dealer” codes

2) Check engine codes

3) “Exhaust system service required” codes

4) Limp Mode codes

5) Other emissions related diagnostic codes


By deleting the factory emission system which has been suffocating your diesel, you’ll immediately notice a night and day difference. It will perform better in every imaginable way, including speed, fuel economy (5 mpg increase on average), and fewer trips to the repair shop.

Over time, the kits pays for itself with the fuel savings alone. That’s not even considering how many costly trips to the dealer you’ll be saving yourself.

The last benefit is peace of mind, knowing your truck no longer has a ticking time bomb attached to it.


Eliminate ALL emissions sensors/components with no codes

  • Diesel Particulate Filter (DPF)
  • Exhaust Gas Recirculation (EGR)
  • Diesel Exhaust Fluid (DEF)
  • Catalytic Converter (CAT)
  • Selective Catalytic Reduction (SCR)
  • Diesel Oxidation Catalyst (DOC)
  • Exhaust Gas Temperature (EGT)

Q: Can I revert back to OEM/Factory settings?

  • Yes! You will have the ability to revert back if needed be via the tuner directly.

Q: Do I have to delete ALL emissions parts?

  • You have to delete the DPF. But all emissions systems are shut off with the tune, so you can unplug any sensors/wiring where applicable. EGR deletes are optional but highly recommended for the best reliability. At the very least make sure to unplug the EGR wiring harness.

Q: Does the tuner need to remain plugged in?

  • Once the delete tune is installed, you can unplug the Mini Maxx. But you'll need it plugged in to shift power levels on the fly and to use its other features. (List of other features at the bottom of the page)

Q: Can I tune multiple trucks?

  • Yes, but only one truck can be deleted at once. The Mini Maxx becomes VIN locked to one truck and will only let you tune another truck if you return the first truck back to factory settings. Our included instructions manual explains how to do this.

Q: Will aftermarket parts like turbos, tires, fuel pumps, etc. mess up my tune?

  • Generally speaking, the Mini Maxx delete tune is not effected by modifications.  If any codes arise you can clear them. You can also re-install the tune anytime if anything unusual happens.

Q: Is the tuner new or refurbished?

  • We only sell brand new products.

Love it

I was torn between the mini maxx and ez lynk tuners. I pulled the trigger on the mini maxx and I'm glad I did. The install took no time at all, the real time monitoring adds a nice touch and for the price it can't be beat.

Talor Seace
Love it

It was quick and easy to understand even for someone with little knowledge

Easy installation

Easy installation, immediate results in throttle response, low end power and drivability. Definitely recommend watching the videos on YouTube so that you won’t miss a step.

Stephen McAvoy

Truck has never run this good. Was skeptical before buying but now definitely a believer. Thanks Diesel Dudes!

Daniel Norris
Super easy install.

From the load to the hard mounting, the install was straight forward and easy to follow.
