Talking Mini Maxx Review

I ordered the Mini Maxx and Delete from Aaron last Monday. I received the tuner on Wednesday and the pipe on Friday just as Aaron told me to expect it. It took me about 30 minutes to remove the DPF/DOC, and then another 30 or so to install the new pipe. Installing the new pipe would have gone much quicker if I knew exactly how it was meant to lay under the truck. The first try, it ended up touching the tranny support, so I flupped it and now it is about an inch from the heat insulation under the cab. But, it is not touching anything so it seems to be fine.

The installation of the tuner itself went real quick. The purple wire is right where I expected it to be. Also, the lext side of the dash just snaps off, along with the portion under the steering wheel. I used removable two sided tape and mounted it at the lower left heand corner of the gauge cluster... not inside the recessed portion, but just on the dash itself. The wire ran conveniently from the inside of the gauge cluster to the back of the programmer. It looks great and the mount (tape) cost $3 at Lowes.

I was pleasantly surprised at the lack of black smoke which I fully expected on the wild tune. I am very impressed with the power, but more importantly, I am very impressed with the way the truck drives now at a quarter to half throttle which is where I typically drive my truck. The shifts are firm, but not jolting. Overall, I am very happy with the results.


I do have a few questions...

What sensors are most important to monitor? I have it set to monitor Pyro one, the tranny temp, coolant and boost.

I see no need to monitor boost, but I am not sure what else I need to keep an eye on. I thought the oil temps would be important, but the tuner always reads 1 degree F. So, I am guessing there is no oil sensor, or the tuner is not reading it.

Also, at what temp should I get worried on the sensors available to me?

Thanks for the help guys. I will get pics up of my truck tonight if I get time. It is a 2010 F250 Lariat 4X4 Black with Black Moto Metal 959s and a Black hard Fold-a-Cover. I am also running 35" trail grapplers. They did not rub at all on the stock wheels, but the offset of the 959s caused them to rub a little... a little trimming fixed that problem.

You may want to monitor EGRTA instead of Pyro 1. The EGRTA is the EGT sensor installed in the up-pipe. Pyro 1 is installed in the DPF delete pipe.

John,

On the Mini-Maxx DPF delete, there are no sensors on the replacement pipe. And, my truck is still reading the Pyro 1 and it seems withing the realm of what i would expect. 400degrees at idle... 700 degrees at 1/4 to 1/2 throttle and up to 1400 degrees at full throttle after a few seconds.

Does this sound right? I am really new to this stuff so I need and appreciate the advise.

Sorry for the misinformation. I forgot that the H&S doesn't use the factory sensors. They also use different abbrivations than everyone else. Those numbers do sound right.

You are correct, the H&S products use Pyro 1 as the pre-turbo EGT reading. Sounds like you have the gauges set up for the most important things. I notice that the factory Coolant temp gauge is highly insensitive and will not show very accurate readings. The programming looks to be more of a "dummy" light than a real gauge, as the temperature can fluxuate as much as 40 degrees and the needle will not budge.

Have fun with the new programmer, and the new found power.

congrats and can't wait to see pics on the mini installed. Also quick question on your tires, I have 18's but do you think 35X12.5 or 295X70 would fit better w/o any level or lift? What size do you have?

I have 35X12.5-20s and they did not rub at all on the stock wheels. The 959s have a different offset and they rubbed just slightly so I trimmed the wheel liner a bit. Either way, a leveler is not needed ona 35" tire.

I am installing a 6 inch lift this weekend... I think I trimmed prematurely.
