Add that to lighter truck with less drag and its way better.
I wasn't considering the transmission change originally

the part that i dont get is that lets say a 3.73 is good off the line ...
3.42 is kinda weaker than 3.73
3.23 sucks ***** ...
3.08 should be smaller than 3.23 correct then it should SLOWER ?? off the line ???
but ppl keep sayin about the 6 spd
i test drove a crew cab 5.3 with 3.42 and 6 spd and it sucked .. so thats what i dont get ....
