I've had my mini maxx for over a month. My mpg hasn't changed alot. It went from 14.4 to 14.8 if I wasn't hauling a load. Once I started hauling it went back down to 14.4 this can't be right my mpg should have increased alot more. Also my mini maxx recently stopped showing the pyro measurements. Idk what to do I have my settings at mild with a 4 for smoke level.

 

I don't know why your PYRO measurement quite working but I get my best MPG with smoke settings at 1 or 0. 14.8 is nothing to cry about as far as I'm concerned.

 

Smoke = incomplete burn of fuel. Turn down the low boost fuel and you'll get better mileage. As far as the pyro, I'm not sure. I'd double check the connections and make sure you have the Pyro 1 set to display.
