I have some questions on injector sizes. I found a website called holderdownperformance. They offer injectors by warren diesel. I am looking for around a stage 2 but they have alot of sizes to choose from. 160cc/30%, 180cc/80%, 200cc/100%, 200cc/200%. These sizes are all the same price so thats not a factor in my decision. What would the power increase be for each and could I run a stock setup for all of them. If so I will be looking in to one of the 200cc injectors. Any info will help, thanks.
