Might need to put new o-rings on the injectors.

I've never gotten over 16mpg. Usually about 12-16 city or highway unloaded and about 8-11 pulling 7000lbs...All hand calculated....I'd love to see 18's though

i'm getting a bit less than 16 avg (city/highway) in my bone stock SRW 4 door 01.
It has the 3:73's tho and 285 tires.

looks like i need to open the exhaust/intake and chip it....

97 F350 see in my Sig. I got 14ish when it was stock, now I get 16.5 mixed, up to 18 straight HWY. All hand calc and I baby it. The 4:10 rear is killing the milage.
