I had another Tuner, Edge Evolution CS2, but the Minimaxx V1 works sooo much better! I have 2009 F350 6.4 Diesel. My truck runs PERFECT now and it has much MORE POWER! Love it!

What Does the Mini Maxx Tuner Do?
The Mini Maxx V2 boosts your truck's performance by increasing power, torque, and fuel efficiency. With it, you can delete several emissions systems, including:
DPF (Diesel Particulate Filter):
The Mini Maxx lets you remove all components of the DPF system while disabling the related sensors and eliminating any check engine lights.
EGR (Exhaust Gas Recirculation):
It disables the EGR function and turns off any related DTCs. Whether you leave the EGR installed or use an EGR block kit, the Mini Maxx has you covered. No more leaks from the EGR!
DEF (Diesel Exhaust Fluid):
This tuner shuts off the urea injection system entirely, so you can remove the DEF tank and sensors, reducing the overall weight of your truck.
With the Mini Maxx, ULSD (Ultra-Low Sulfur Diesel) becomes optional, allowing you to run high-sulfur diesel fuels if you prefer.

MINI MAXX V2 Power Levels
The Mini Maxx V2 does not use fixed, published horsepower presets (such as “Mild / Wild / Hot”) like earlier versions. Instead, power output is controlled through vehicle-specific tuning files, allowing adjustable performance based on the selected tune, engine platform and supporting modifications.
Depending on application, Mini Maxx V2 tuning is commonly reported to provide moderate to high performance gains with increases typically ranging from approximately +50 HP up to +150 HP and in some cases higher when paired with advanced tuning configurations. Actual results vary by vehicle year, engine and calibration used.
The V2 platform emphasizes flexibility and customization rather than fixed power stages like the V1, allowing users to balance power, drivability and efficiency through selectable tuning options.

Quality products with awesome prices .
Good quality, quick to install.
It’s rlly good deleted my truck in secands
Night and day difference, I had Spartan N Dash before I bought this H&S.
It is definitely worth it. Truck runs better with no worries of DEF heater leaving me stranded. Put about 6000 miles on it no problems.
Super easy install. Best price online. Cleared my dpf codes no problem. The power increase is very impressive. Tuner was shipped quickly.
Purchased the system for my 2017 F350, mainly because a buddy said I would get better fuel mileage! While that is the furthest from the truth, I relish in the increased power and loud exhaust to scare the slow people who don’t know what a speed limit is. I purchased 36.5 tires for my truck and liked that the Mini Max V2 was able to calibrate for the larger tires and lower tire pressure requirements. Over all, quite pleased.
Plug and play super easy! Added this tuner along with their Egr and dpf delete. Amazing sound and power levels. No professional help needed.
I am not a certified mechanic and the Mini Maxx was simple to install and very easy to tune and delete my 2009 Dodge 3500 6.7 Cummins Diesel. I have increased my performance on horsepower and mileage on both the performance setting and the tow setting. I am very impressed with this product and recommend it as well.
Probably was the Best Decision I’ve made! Let me tell you , This mini Maxx did things for my truck that thousands and thousands of dollars can’t do! I highly recommend this unit for any GMC Duramax owners especially to get ride of all the check engine issues related to the emissions system. Worked perfectly for me .
Tuner works great, i do have a couple questions for someone if they could get ahold of me though! Would be greatly appreciated.
Still playing with it. Don't like there is no manual. Have to go screen by screen. When first installed I thought something was wrong because where the power levels are shown it said No Power. I thought it was the tuner or my truck. It ended up being one of the power levels. All in all easy to install and placed my unit down by my right knee at the little pocket there. Still easy to access and not visible from the outside.It did clear up all my problems so far. Waiting to pull my trailer so see the difference.
Works exactly as advertised. 👍🏻
The tuner really woke the truck up. It’s a big difference like night and day. And especially the delete with 4” Exhaust. Truck sounds like a jet ready to take off now. Great purchase
Everything was as expected works perfectly the install was pretty easy and didnt take long at all
Great product! I chose the standard tune for my 2016 6.7 powerstroke. It went in easily and now I have no more check engine light for faulty DEF components. What I like about this tuner is it does not need to be left plugged in to the OBD port. I just want my truck to run as it should at the factory settings and this product seems to have done the trick.
product specified that it would work on my 2014 ram 5500 cab and chassis. installed it and immediatly had a urea code. tried to call tuner depot but was told i need to email them with my issue. after emailing i got a response that it wasnt the tuner but the truck with the problem. brought the truck to a diesel shop, had them install a CORECT tune file with no issues. do not recommend this product. a complete waste of $900!!!!!
Wow woke up my super duty
TUNER DEPOT IS AMAZING!!
Fuel mileage pickup around 2 mpg in town. Work's great haven't pulled anything yet but think it'll be ok. Let problem get it the first one got lost gave customer service a call and they sent me another one right out had it in 3 days . That was great customer service!
Works great. Downloaded perfectly. Does as expected. I personally was not looking for performance, I had a display that was to reduce speed in 45ish miles. Installed in a off road toy truck and didn’t need speed reduced Worked exactly as I needed
N/A
Worked great with no issues.
Didn’t work correctly with original card or with replacemen card. My truck is sitting in my shop for 3 weeks now with no fix! Have been waiting on return envelope for 5 days
More power now it get up and go.
Great product, gas saving and more power.. thx
Plug and play as described. I too have a V1 in another truck, the V2 was an easier install and download.
Great
Very helpful throughout the whole process!
works great and was easy to install
Everything went together, just had to search up YouTube videos how to program
It was super easy to install. It works great.
Easy installation love the extra benefits it gives as well just curious why I’m getting a p2457 code now
EVERY THING WORKS GREAT, EASY INSTALLATION AND GREAT HELP WHENEVER AN ISSUE ARISES. PURCHASED MULTIPLE ITEMS FOR MULTIPLE TRUCKS AND WILL CONTINUE TO USE THEM FOR FUTURE PURCHASES.
Works great as always
