Save Big when you buy an H&S Performance Mini Maxx Tuner with Pyrometer paired with a FloPro DPF Delete Exhaust for your 6.6L Duramax-powered Chevy Silverado or GMC Sierra pickup truck. The Mini Maxx is packed with all the same features and performance as its big brother the Black Maxx – the only difference is a smaller but still fully functional screen. The Mini Maxx allows the removal of the DPF, Urea Injection and ALL related sensors if desired. Your entire EGR system, including cooler, can be removed — or simply switched off — code free! The Mini Maxx comes with DPF Present & DPF Removed tuning modes, and with four different power levels, you can experience rear wheel horse-power increases up to +175 over stock!

To finish off your race machine, you need a high quality dpf delete exhaust system from FloPro. FloPro exhausts are made to fit right every time, and come in a variety of configurations and materials to meet your exhaust needs. Manufactured to exacting standards in North America, not cheaply mass produced in China like many inferior exhausts, FloPro DPF delete race exhausts come with high quality hangers and clamps.

6.6L Duramax LML Mini Maxx Specific Notes

  • Power levels are NOT shift-on-the-fly. It may take up to 10 minutes to change tunes. Check here for software updates. This also means the Mini Maxx will NOT defuel on its own. A built in warning showing “WARNING PYRO 1” or similar where it would normally defuel.
  • The EGR and UREA main harness must be unplugged, while the DPF Pressure Sensor must remain plugged-in to gain full horsepower when running in DPF Removed mode. Instructions for these requirements can be found here:
  • Periodic emissions checks are performed by the truck’s PCM. While doing so the dash may display “Service exhaust fluid, see owners manual” if the the vehicle has recently been reflashed or has not been run in a while. This message will clear itself as soon as the emissions check is complete and can be ignored. Check here for software updates.
  • Tire size is NOT yet adjustable. H&S is working on an update to add this in a future software release. Check here for updates to this issue.
  • The Speed Limiter is allowed to be removed but will cause loss of cruise control functionality. The Speed Limiter is capped at 96mph. Until an update for this issue is available, the choice to go over 96mph or to use the cruise control is yours to make.
  • Exhaust kits right now are ONLY available in CAT back kits. This is due to the extreme embedded nature of the down-pipe. For those who have a shop or the ability to cut, modify, & weld to get to this area, the LMM Downpipe Kit can be modified and used.

Important Note: This purchase price includes the cost of the 6.6L Duramax LML software unlock code part 111006. When ordering, include your complete VIN # in the “Order Comments” of your shopping cart. Your unlock code will be emailed to you.

Please Note: The H&S Performance Mini Maxx is capable of disabling all or part of the emissions control systems on your diesel truck, if you choose to do so. Emissions removal is not legal in the USA, unless the vehicle is not registered with the DMV, and is being used solely as a competition race vehicle. Its use is limited to closed-course racing that is formally sanctioned by a recognized racing organization. Any other use, including recreational off-road use, could be in violation of local, state and federal laws. This is a Race Only product used solely for competition.
