The Official Superchips Forum

i have had the tuner on for about 2 months like everyone else on here the first 2-3tanks of gas was me making sure it worked ok...lol. however i added up the mpg when i "making sure" also took note of the stock tune mpg, and other tanks now that i know it works. and i have the same mpg... i also tried the different tunes.. i still have the same mpg no matter what tune, or if im driving like a stole it, or out for a sunday drive. i get around 311 per 22 gal or 14-15 mpg, witch is what i got stock.

i do have a few basic mod to the motor...k&n cai 63 series, true dual exhaust(glass packs) with an h-pipe, e fans, e3 spark plugs, and accel supercoils. the truck runs great fast response and ect. but the mpg kinda *h thru.

i am using the flashpaq, i have updated it about a week ago. i do use 93 octane. my tires are stock, other then what i listed above everything else is stock. thanks for any help.

Welcome to Superchip's Forum!!

Mpg gains are hard to get on a full size truck with such a small motor.

On the 2007 truck the performance mode yields the most power (15hp and 17ftlbs)
This would be your best bet to try. But, there is not much more that you can do with the tuning.

So the mods were on the truck prior to the tuning?

yes they was, actually the supercoils where put in right before. i wanted to make sure all the hard parts where done with before i tuned. what im wondering is way the extra mods didnt help at all, maybe i took to much back pessure off the motor. oh this does a lower degree stat and an aux oil cooler(not trans) it doesnt run over 180-190, i also thout this might an issue with it running to cool. but i just got a 2009 f150 with the same motor all factory for now the est mpg says 14.1 i will see if its right when i add the actual mileage vs gallons up. if its the same then it may just be like you said very little mpg gains. im not worried with it i was just making sure everything was right with the tuning.

thanks for the help.
