Hello. I'm new to the forum. I've had my 2015 F250 SD for a couple of years and thought it was time to do some mods. I purchased a H&S Mini Maxx and installed it this afternoon. Stock truck + Stock Emissions. I will have the emission work done this week to delete the DPF, CAT, and EGR. In the meantime, I wanted to try out the emission tunes. All is good when I load the tune, but unable to shift on the fly. I loaded the stock setting in the install and I noticed maybe a small amount of power increase. When I would use the button to move up to the other tunes, no change in power. I re-installed the performance tune and definitely a noticeable increase in power, but when I go back to stock on the display, the power stays the same. This is a fresh install from a new purchase. Any suggestions? Help would be much appreciated.
Did you ever figure this out? I just installed a Mini Max on my 2015 and mine does the same thing. Kinda sucks you have to reflash for each power level. Not even sure how these are still sold new since H&S closed shop thx to epa.
That's what happens when you buy something that doesn't work for your model year truck. H&S never supported the 2015+ trucks. Anyone selling you such a "H&S" device stole your money.
Apparently H&S is still doing business outside the US and got the 2015 to work with the MM. SOTF doesn't work but my truck runs amazing with tunes installed so they didn't steal my money, just not quite as advertised.
