Mini Maxx & Other
RAM MEGA CAB | WHAT DELETE PIPE DO I NEED?
What DPF delete pipe do I need for my Ram Mega Cab?
The Dodge Ram Mega Cab uses the same DPF delete pipe as the short bed or crew cab long bed. Under Make Selection: Select "normal pickup"
H&S MINI MAXX | YES, IT WILL FIT A 2015 POWERSTROKE
The H&S Mini Maxx will work on the 2008-2016 Ford Powerstroke Diesel. It's common knowledge the H&S Mini Maxx will work up to 2014. Rumors on forums and miss informed dealers/installers seem to think development of tunes stopped after 2014. However thats not the case. Our tuners are Fully up to date with the latest 2015 Powerstroke tunes available. See blog post on 2016 Powerstroke before purchasing for that year.
Tech support & 1 year warranty are also included.
H&S MINI MAXX | CHECK ENGINE LIGHT STILL ON
The most common issue and overlooked thing when installing the H&S Mini Maxx is thinking the tune has been installed when in fact it has not been.
If your check engine light is on after installing; 99% of the time its because you didn't not follow the on screen instructions properly. Read & Clear the Diagnostic Trouble Codes (DTC's). If codes and check engine light are still on; verify the tune status: Go into the Menu < Settings < Tune Status.
If tune status shows "Not Installed" go back and reinstall. It will ask if the DPF is present or DPF removed. Be sure to select DPF removed.
H&S MINI MAXX | VEHICLE SELECTION INFINITE LOOP
When installing the H&S Mini Maxx you must select your vehicle to load the proper tunes. In some instances it will continually keep asking even though you may have already selected it multiple times. This is a known issue, a rare issue, but we have seen it a handful of times. Send back the screen for warranty and we can swap it out for a new unit.
H&S MINI MAXX | WILL NOT WORK ON 2015+ DURAMAX LML
The H&S Mini Maxx will not work on a 2015 truck. For some unknown reason people purchase the Mini Maxx thinking it will work on a 2015+ GM Duramax. It will not. The Mini Maxx will only work on the 2011-2014 LML Duramax. Check your VIN before purchasing. The 10th digit will tell you the year. 2013 = D, 2014 = E, 2015 = F, 2016 = G. The pic below is the screen you will come across if attempting to install on a 2015+ model year truck.
H&S MINI MAXX | UNRECOGNIZED PART NUMBER SPRA020.MM SPARTAN TUNER
If when attempting to install an H&S Mini Maxx you come across Unrecognized Part Number "SPRAxxxx.MM" this indicated that a Spartan Tuner has been previously installed on the PCM. Spartan Tuners essentially hijack the the PCM and leave a footprint that prevents other devices from being downloaded. The truck needs to be re-flashed back to stock or "as built". Typically a diesel repair shop or dealer can take care of this using an Integrated Diagnostic System (IDS). After the PCM has been flashed back to stock as it came from the factory you can install the H&S Mini Maxx.
Mini Maxx Tuner is stuck on initializing communication
Simply press the top left button on tuner. If that does not work try unplugging and re-plugging in tuner and then retry.
H&S MINI MAXX | UNRECOGNIZED PART NUMBER ON 6.7L POWERSTROKE
If when attempting to install an H&S Mini Maxx on your powerstroke and you come across Unrecognized Part Number, Plug sd card into computer then go to 6.7L Ford folder, click on it and find closest part# to the unrecognized part#, rename that file to the unrecognized part number, put sd card back in tuner and re select (year) of Ford truck then go to install download and it should go through.
H&S MINI MAXX | DURAMAX ERROR CODES 312 & 316
When attempting to install an H&S Mini Maxx on your 07-10 Duramax and you get code 312, go to show settings & hold down bottom left key 10 seconds then a screen will pop up. Enter unlock code 0468.
Then select reset unit then go directly to install down load, do NOT re select truck and year.
Error code 316:
This code means that the tuner isn't communication with my ECM and there must be a tune on the truck or has been a tune on it in the past. Your truck will first need flashed back to stock at your local dealer before before the Mini Maxx will install.
DPF DELETE EXHAUST | AM I MISSING A HANGER?
Chances are your most likely not missing a exhaust hanger. A DPF Delete exhaust system is substantially lighter than the factory Diesel Particulate Filter (DPF). Since the weight of the DPF no longer needs to be supported the need for a hanger is no longer required.
SCR SYSTEM DELETE
Doing a SCR system delete is one of the best things you can do to increase the life of your diesel pickup truck. Improve reliability and dependability by getting rid one of the weakest links on the Ford Powerstroke, Ram Cummins & GM Duramax. Removing the SCR will also make it so you no longer need to run Diesel Exhaust Fluid (DEF). The SCR and DPF are deleted together and must be done with a DPF delete capable tuner.
SHIPPING DAMAGE | MAKE IT WORK VS INSURANCE CLAIM
Shipping a +80lb. box from one end of the country comes with its downsides. Sometimes the ends of exhaust pipes get bent or damaged. In most cases this can be easily fixed with a large crescent wrench. Other times it can look like a bomb exploded. If you get an exhaust system that's beyond repair, let us know and we will get it taken care of.
STAINLESS EXHAUST RUSTING | T-304 VS T-409
The majority of stainless exhaust systems on the market are made from T-409 stainless steel. Every stainless exhaust kit we sell is T-409. After a few months or years; depending on road conditions and the environment your exhaust will eventually accumulate surface rust. The best thing you can do is occasionally clean it up with a scotch brite pad. The only way to prevent any sort of rust is purchasing a T-304 mirror finish exhaust system. These kits will typically cost you 2-3x more.
2015 OR 2015.5 DURAMAX LML | CHOOSE THE CORRECT EXHAUST SYSTEM
2015 was a split year for the GM Duramax. 2011-2015 the downpipe was attached the turbo-direct pipe using a v-band clamp. 2015.5-2016 the downpipe was attached using a 3 bolt flange. Before purchasing a new DPF delete exhaust system be sure to visually verify the clamp style your truck is equipped with.
H&S MINI MAXX | CRANKCASE CODE 2016 FORD POWERSTROKE DIESEL 6.7L
The H&S Mini Maxx will work on the 2008-2016 Ford Powerstroke. Some 2016 trucks are equipped with a crankcase ventilation sensor. When installing the H&S Mini Maxx this will set a check engine light & DTC. The truck will still run properly but you will have a check engine light.

SCR DELETE | 2013+ DODGE CUMMINS 6.7L
The Ram Cummins 6.7 is equipped with a Selective Catalytic Reduction (SCR) system. The SCR system requires the use of Diesel Exhaust Fluid (DEF). DEF is injected into the SCR catalyst where a reduction reaction occurs, converting nitrous oxides into water and nitrogen gas. This reduces both the EGR and DPF regeneration duty cycles. When a truck is new with low mileage this system works relatively well. If your having issues with your DPF & SCR and dont want to spend thousands of dollars only to have it fail later on down the road; consider removing it completely and doing a DPF/SCR delete.
