I was tired of constant regen cycles ruining my fuel mileage. After installing this tuner and deleting the DPF, my MPG went up significantly. The interface is simple to use, and being able to monitor my EGTs on the fly gives me total peace of mind.

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 .

The exhaust components fit perfectly with zero modifications needed. The Mini Maxx V2 is compact but packed with features. I love being able to monitor all my parameters in real-time. If you’re on the fence about deleting, just do it with this kit.

After constantly dealing with DEF system errors, I finally pulled the trigger on this kit. Best decision ever. No more codes, no more limp mode, and the power gains are incredible. The display looks clean on the dash and is very intuitive to navigate.

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!

I was a bit skeptical at first, but this kit completely transformed my truck. The installation instructions were crystal clear, and the Mini Maxx V2 worked flawlessly right out of the box. My fuel mileage has improved significantly, and the throttle response is night and day. Highly recommend!

Great product easy to install

The reroute kit was high quality and easy to assemble it really cleaned up the space on my 2014 lml .

The price doesn’t Reflect on the product. Very high quality heavy duty parts . The only thing lacking is instructions that would have put this kit over the top . I did the full lml delete and pcv reroute . The kit doesn’t come with the up pipe you have to order that separate.

Better sound, more power. Love it!

Purchased SPE delete for a F450. Was a little more than I could do to install. Took to my mechanic who installed it. He couldn't stop raving about the quality of the kit, and the difference it made in the truck's performance. This truck would endlessly code saying "cleaning exhaust filter" over and over. All of that nonsense is gone, the truck runs 100% better. AND went from 8.9 mpg to 15.1 mpg! Overly satisfied!

Everything went together good besides having to figure out the installation with only pictures. A video or better installation instructions would have been very helpful. Truck runs and sounds great now!

I was a little scared it would make the truck sound like a soda can but it actually sounds deeper and way better so I can’t complain easy to install ( if you have the long bed you may need to cut back 4” off one of the middle pipes to get the hangers to line up very easy solution make sure you cut the side that doesn’t have a bell end)

be sure to update mini Maxx with the latest firmware 2.0.0.8 FIRST! I learned that lesson😟
I also on my 2019 ram ended up plugging OBD bypass into middle row fourth one up after doing that I got zero codes truck runs great !! customer service isn't a whole lot of help mini maxx responds to emails but not quickly.

The product is great. Does what it's designed to do.
The instructions? Not so much. Luckily, the Customer Service people do their best when emailed and walk you through the process start to finish. The only other thing I'd like to see are the basic beginning settings for setting up "defuel". Every engine is different (Ford/Chevy/Dodge) and finding this info through forums is terrible.

I currently have the DPF deleted, the EGR turned off, and the race pipe has a 27" stainless resonator added to keep it quiet. It rolls coal on "Extreme" and the increase in power on "Stock" is very apparent. I run it on "Stock" 100% of the time and gained over 2 mpg so far on the first tank.

2013 F350 Crew Cab Dually 50225 miles on odometer. No rust anywhere, pristine Cali truck. I guess the original owner couldn't afford to drive it. LOL
