If your gonna keep the truck stock, like a 96-98.5 5speed is your best choice because they have a 215hp pump. But once you start to upgrade the truck like a fuel plate, turbo and all this.The smaller pumps like a 160hp pump is better because they are less toucher in the throttle. But other then that, its all the same

 

yea no problem, just let me know what you need to see.

 

on upir 94 cummins, do you have a sensor in the top middle of your diff, if so where are the wires that are connected going on the truck?
