Quad Max Mileage
 

ok I have done a weeks worth of testing with this and am very happy with it. I gained 1.3 MPG. truck idles smoother and shifts nicer and seems to have a little more power through out the ranges.
I aquired two max mileages some how lol. I forget what i trade these days. so look for that one in the classifieds soon.

but I am going to try the city tune to see if I see more gains.
I am running a roktech sensor with it but am worried that the timeing they put into the city tune will be too much. They say on quads site that the city tune will make the motor louder at lower RPMs until the turbo spools. do you think the ROKKTECH will be too much?

how does this box differ from the smarty sr on lvl 1? could you stack these 2 and get better millage? i love the smarty but i am looking for better mpg's

it wouldnt do much for you. its meant to be a stand alone module. you could pay $60 and get the xzt (60hp) and have a little more power and get the stcking tune. But I'm not sure what you would see in MPG increase
