both.......
like i said i have 4:10 gears, and i have not met anyone yet, who is getting that mpg. i know people are getting those numbers, but from the guys i know, they are impressed. i wish that PPE made the 'hot' in the 2006 model, but not yet... ... ... as to the fuel running low, i know its not the smartest thing to do, but i haven't taken my chances lately... ... . i've heard that the 'draw straw' from the airdog will not get that last bit of juice from the tank if the truck is positioned certain ways... ... ..... mostly downhills. hey wags, totally not trying to diss the smarty, i know it is a sweet piece. my friends have kept up with the latest downloads, but they still smoke more than i do, especially at take off. went to a dyno run earlier this summer and all i kept hearing was that i wasn't getting enough fuel... . yet, i was pulling the same hp numbers as the guys running the smarty. again, the smarty is a sweet piece and from seeing all the threads on the forums, i know that people like it, but to each his own.
