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.

Function is great, a bit breakable
Style: Classic, Size: 26in
This is probably the 3rd or 4th of this we've bought which reflects pros and cons--it is a great thrower, easy to use and great for keeping your hands clean with a dog who loves to play fetch! The con is that they're a bit brittle. We've broken a couple just smacking the plastic against a sidewalk, so you just have to be a little careful. Our puppy chewed on another one and destroyed it, so you might want to keep it out of the reach of your dogs when you're not using it!

Best toy EVER for a very active dog!
Style: Classic, Size: 26in
This is the best item I've purchased for my young Mini Schnauzer. He absolutely loves that I can now pitch the tennis ball quite a ways and he gets loads of running time. He begs for me to use this toy for him . . . he LOVES it! Easy on the arm as well!

Our dogs love it
Style: Classic, Size: 26in
On one of our trips to the dog park we saw someone using one of these with their dogs, it looked pretty neat and the ball flew so much farther than by hand. It wasn't very long before our dog got caught up in the excitement and joined the pack running after the tennis ball. Our dog stood with the rest of the dogs at the park staring at the ball in this launcher and waiting for the lady to throw it, once thrown the entire pack raced across the park after the ball,...they loved it! I decided to buy our own after watching and seeing how much fun they were having. This arrived a couple of days after I ordered it, and what struck me as funny was our dog recognized it as the toy from the dog park as soon as I pulled it out of the box. She couldn't wait to play. There is a small learning curve, but after a few trial throws I got the hang of it. This 26M launcher is a little large for me, it works but seems to work out better for my husband. I am going to order the smaller 18M size for myself. Both of our dogs had a great time, we had them running all over the place chasing after the ball. It was great being able to tire them out! With this launcher you can throw the ball farther and faster than you can by hand. Being able to scoop the ball up without having to touch it is a bonus, especially when the ball returns full of dirt and dog drool! This ball launcher can also be used with regular tennis balls too so if the ball that comes with the launcher gets lost it is easily replaced. Perfect toy for tiring out our dogs! *Update 9/24/16- I ordered the Junior 18M, it works so much better for me. The longer length of the 26M was starting to make my wrist sore, however my husband has had no issues. I'm 5'4" and my husband is 6'3" in case this info helps anyone make a decision on which one to buy. I know I went back and forth trying to figure out which one, which is why we now have two. ;)

If you were looking for a sign to buy this, here it is
Color: A) Small 2.5" Ball
If you are looking for a ball that can stand up next to a heavy, aggressive chewer.. this is a good choice. Our Pitbull literally destroyed any and every toy that she gets with the exception of one kind of kong ball. She tore through the kong Frisbees, any kind of squeaker toy, and the wobble wag giggle ball (she usually always ends up destroying these but it takes a few weeks. Today she beat her record and had her brand new ball destroyed within the first 30 minutes of us taking it out of the box). But, this ball she has not been able to destroy. I'd like to believe that the Kong ball she has and this ball are made of the same material. Because they are the only balls she can't ruin. And it's not because of a lack of trying. We have watched her sit there and chew with a side of her mouth for an hour or more, trying to make some kind of indention or tear in it and it just never happened. She loves to chew this thing, chase this thing, sleep with this thing. I most certainly recommend this ball. If it is I'ah proof then it is most certainly, 100% a durable ball and worth every penny

Chew King Supreme Chew Toy
Color: B) Medium 3" Ball
So far, freaking amazing. This ball is awesome. I have a 90 lb American Bulldog. Like other reviews. Lot of " indestructible balls" lasted minimum time. Not this one. She even took it to bed with her I bought the 3 inch ball, not the 4 inch ball. The 3 inch ball works amazingly for a large Dog. Yes the 4 inch would be better. So in my opinion, either ball would be fine. As others also said. This ball keeps a active Dog busy for hours. Love to play catch. Love frozen peanut butter in it. One last thing. The price is amazing. I don't see needing to buy another, unless it is lost, because this is made to last. We couldn't be happier.
