ok so the truck was getting 16.8mpg on the digital reader
and all of the sudden it is getting 11.2mpg, wth??
the truck has 4 inch turbo back exhaust, cfm manifold, di cross over line, DIY intake, Boost fooler(not the diode).

anyone know what could be going on?
the truck was getting 18mpg around town, 21 or more highway before the chip was sent out,
the mpg with out the the chip 16.8 now 11.2?
:dunno: the last three things put on (in order) were di x over, diy intake, the boost fooler, things seemed good until the boost fooler but that was put on after the chip was sent out

You pulled the chip off...


And think of the fuel you could have bought without paying the $400 bucks for the CFM intake

it got 16 without the chip for a good week and a half though is the odd thing. yeah i know it was right when they came out, would deffinitly not reccomend it. all it did was add a couple hwy mpg
