fuel mileage

[m0823]

Wondering if what i am getting is too low. Only mods are the foil delete, diy intake, and muffler delete. although i just got the intake done today but without the intake ive gotten about 13.5mpg. I will update after this next fuel tank with the intake but even without the intake is 13.5 too low? This is with no load at all just leisure driving, maybe about 250km highway of the 650km i get to the tank. This is hand calculated by the way.

ALSO original papers from trucks purchase says it has limited slip 3.73 rear-end

That's about what I'm getting. I have the 6637 filter and diy intake, turbo back 4" with magnaflow big truck muffler. 13.5 average over 10 tanks, mixed highway (high of 19.5) and city (low of 12.5).

What size tires? Auto or Manual? are you shifting at or below 2000 rpm? and could have alot to do with the type of driving your doing.....

i get the 13.5 as an average over the entire fuel tank with maybe a 1/3 of the driving highway
