Advice on new Mini Maxx

tony97gt · #1 (**permalink**) 07-26-2012, 09:44 AM

I just purchased a used mini maxx from a member here. Once I get it, do any of you guys have advice on how to set it up? With it he sold me the DPF delete pipe so I can go right into no DPF setup. What do I do with he sensors that are on the DPF now?

Any advice on mounting the minimaxx? I was looking into the side mount right above the a/c vent near the light switch. Is that where most guys are mounting them? What is the cheapest place to buy that mount?

I've been told I should back-up my stock tune to my laptop incase my mini gets stolen or damaged.

Also, I still have to stock intake. Should I upgrade to the S&B or which is the better intake. I know I'm probably asking a rhetorical question here...

The h&s doesn't need those sensors when you are running the dpf delete tune. I had a delete pipe with bungs so when I installed the h&s I just left the sensors plugged into the delete pipe. I recently changed my exhaust system and got the pipe without bungs so I just unplugged those 4 sensors and ziptied them up out of the way. I have just left mine on the windshield with the suction cup that comes with it. I didn't back up my stock tune but I haven't heard anyone say that you should. Also I am still running the stock intake with an afe drop in filter. I eventually plan on doing a cold air intake but have just been investing in other presents.

no need to back up your stock file. it is stored in the mini maxx along with all the other stock files.

if yours were to get stolen, you could just buy another mini maxx and load it up and then return it to stock

The used tuner. Go to h&s website and update it with the automatic updater and get it ready to install. Go ahead and plug it into truck and let it boot up. Go to menu and update firmware. Once that's done download the tune to the truck by following the on screen instructions. U will be able to pick what tunes u want and dpf on or off etc. once you do all that start the truck and make sure the tune went through and it runs. Shut it down and move to the exhaust. Unplug all sensors under the truck on the dpf but leave the sensors in the dpf. Once u get all 4 unplugged remove the band clamp at the tail section end of dpf and remove the rear tail section. Then go to the front of the dpf where it connects to down pipe and remove the two bolts from the front side of the flange, the side of the flange towards the dpf has nuts on that side that are welded so no need to get a wrench on that side. Get a 13mm swivel socket with3" extension and u should be able to get both bolts from the down pipe side of the flange. Once the dpf is loose, hit the rubber grommets with penetrating oil or wd40 so they will slide off easier. Support the dpf with floor jack if doing it by your self, it's kinda heavy. Use pliers if you have to pry the hangers out of the grommet. It's not too bad to do at all

Sorry for the long post

I just did the exhaust removal a couple days ago & holy man was the tailpipe section a pain to get out by myself. I ended up jacking up the truck with the little jack that comes with it and that skinny little thing looked real sketchy so I got it up just high enough to remove the tire. Then I had room to get it out.

Thanks for all the input guys. I will probably not be doing this by myself. I can't wait to get this stuff on and see the difference. Although my MPG is gonna go way down...I can barely keep my foot out of it stock, once it gets tuned it's gonna be even worse.
