i realize i am beating a dead horse here

the exhaust and intake will be on this week,

after my guages i want to get a box for better mileage and towing

nothing fancy just a one setting, simple plug in box, i was looking at the granatelli milage monster (which i understand may be a rebadged quad box)
only because they are going to guarantee 3 mpg

is there something else i should look at that would return similar mileage gains
or that would be better for towing

i see that the quad xzt is recommended by a lot of guys is that the same as the granatelli? is the granatelli running a different program
