I have an 08 f350 with a mini maxx, s&b intake, 4" exhaust,flo pro cold side pipe. I run the easy street tune(120) and sometimes turn it up to the performance (175) Sometimes when I'm really pouring the fuel into it whether towing( using the tow tune) or passing the truck falls on its face. Its like the tune cuts out and I lose most of my power. My friend has a 2010 with a mini maxx and 5" exhaust and it does the same thing? I get no message from the tuner saying de-fueling or anything? Any ideas?

Could be the tranny defueling, won't show up on tuner, it's a factory thing.

I figured if I was hitting a de-fuel setting it would show up on the tuner?
