it all depends on where you truck is. your gunna get more power from aftermarket sticks from a truck with other power power upgrades than a stock truck.

435 means 435 horse total. Kinda a guess really. I would agree they could make 435 horsepower if you had the fuel supply and cool air to go with it.

6x16's and 6x18's are basically as big as anyone could ask for. They will support as much power as you can feed them. Most of the big boys run the 6x16 and 6x18's.

after reading your sig , 2 questions come to mind ;

how much pressure is your lift pump feeding into your injection pump ?

what kind of turbo are you running ?

Yeah, it's hard for me to imagine how even modest injectors would not make a dramatic power improvement to an even slightly modded truck.
