with better dv's you will get more flow to injectors, but not gonna help you with stock sticks! you dont need dv's to make more power

whats all done to your truck, laser cuts and a full cuts are more for competion, 191s, 181s, and .22 .24 are good for a dd, i would get bigger injectors before you start messing with the dvs imo

Delivery valves will flow more fuel even with stock injectors. As you go up in delivery valve size you inject fuel over a longer period of time.

thanks, i just saw that the DVs were pretty cheap and thought that it would b an easy way to make power, but i dont plan on doing much more than 75hp injectors and MAYBE a larger turbo... for now

the larger turbo is the dodgezilla and the dv's and injectors im gettin from southern diesel if u aint goin over 75 horsepower go to citidiesel and look at the 370 injectors the only problem is the spray angle with them if u want 100 hp injectors go to pensacola diesel they have 100 hp remans for 200$ a set
