Tell me what you know about the ol' Duramax's

[sierraman]

and 2 of these trucks are in the shop getting new pistons right now, and one a new head...lol.... go cummins

first off, i will say that anything can do wonders when the right parts are added to it, especially a dmax. i love the ride comfort and interior of the 03-06 gm truck/suv's just as much as anyone. as far as your friends trucks,
i would have to chalk that up to not matching up parts properly, and possibly poor tuning on the owners part.

secondly i work at a dodge dealership i get calls all the time about people braking stuff. mainly the #4 injector line, i mean it only has 26,000 psi from the factory and when you up the turn up the pressure, it can't hold.

i viewed first hand every weekend my friends 04 dodge 3/4 ton 5.9L, 6spd, 4x4 on 35*14*r20 : it had oversized pump and injectors, 5" exhaust, drop in k&n, and superchips programmer. we loaded down the 32 ft' enclosed with car and 4wheeler, we would stomp the 1 ton duallys with 20' open trailers all the way to the track and still got 18mpg. when we unloaded and it was just the truck, we averaged 25mpg doing 70mph. i have seen this truck burried to the frame and still be able to pull itself out of the mudhole. i have seen his truck pull 2, yes 2, half-ton trucks out at the same time of a muddy pasture.

sorry for the rant, but that is all i want to say on the matter. i really don't want to start and an arguement over nothing.
