specktator - 20-25 out of an lmm is hard to believe, now Im talking about calculated mileage not what the dic is showing & what color is ya d-max?? I seen a guy that kinda looks like you when I flew into laffy few weeks back, he was pullin a trailer I believe and talkin about goin fishing offshore??? just wondering??

Thats what this guy told me. Maybe its a different programmer. He actually told me he got like 27mpg but I dont know if he was blowing smoke up my arse. He said he could smoke the tires at like 60mph. And he said if u cut off that big tuba for a muffler that comes stock and put on a straight, u would get 3-5 mph just off doing that.

I have a white one and have a Salty Cajun and CCA sticker on the back glass. I love it besides the fuel mileage and tiny fuel tank. (24 gallons!) I got some BFG mud terrains on mine so the mpg is even worse. Been looking into getting a programmer, but I dont know much about all that.
