If you're not going to delete the dpf I wouldn't run a tuner at all. From what I've heard the added fuel causes more soot clogging the after treatment system resulting in more regens. And I learned the hard way that even if you remove the tuner for trips to the dealer, of the look they will find the footprint. They can't see anything from the actual tuner but they can see how many times the ECM has been flashed and if that number doesn't jive with the records it'll throw a red flag.

That being said, I am VERY happy with my h&s mini maxx no problems whatsoever and great power. No matter what you decide to do you'll be happy.

Best of luck!!

^ this!

If you add all that fuel and timing without deleting the emmisons, you'll cause the engine to burn up.

I deleted my truck with my MIni Maxx, didnt hook up the pyro, and kept my stock parts do I could just throw them back on for trips to the dealer. One instance when I did just that they told me that they noticed an excessive number of ECM flashes on my truck and they had somehow stored the data and were going to look more into it. A few weeks later the pinion seal started leaking so I took it to a different dealer since I was working out of town and the service manager told me that my warranty had been "flagged" not voided but I was on the watch list so to speak and still made me pay to have the seal changed. So, at that point I knew my days were numbered. After that more and more stuff started getting denied on warranty like my leaky trans pan gasket they said it was "normal wear" I eventually got fed up with their crap and went all out and haven't looked back since.

Slight. I'd say 2mpg plus or minus. Might be better if you can keep your foot out of it. Once I woke the truck up I have a problem keeping my foot out of it :P

Yes, but with a tuner, it's going to be tough to keep your foot out of it.

And i wouldn't use any other tuner but EFI live.
