i was at an average of 10.8 miles to the gallon city not real sure highway since i dont get on it much. i just installed an air raid cold air kit a magnaflow dual exhaust and did a synthetic oil change and with the combo of parts i now average 14.4 miles to the gallon city. for me the $1000 i spent is worth added milage plus the truck just sounds MEAN! thanks for the help picking the parts everyone

 

zero out the average MPG reading and drive a few hundred miles and come back with your results...


with the CAI and exhaust, you should also chip in and buy a programmer for your H2.

i think after a few humdred miles, ( and after you zero your Avg MPG) you will have a more accurate reading.

what size tires are you running? 35 inch (stock) or bigger? or smaller?

 

they are the stock size bfg tires and i zero the milage on every fill up i was holding strong at 14mpg but now my foot is getting a little heavy cause i love the sound of the exhaust and the extra power. for the programmer what is best for our trucks thanks for the help

 

Thats great man! Anything in that department will help the engine do better! Remember shes a big air pump and the best way to make it run better is to get air in easier and air out easier!
