Hello, I know I may catch hell for this but here it goes. I talked to Rene at quick tricks one day and he told me some interesting info. He said he has been doing a lot of test trying different things out to see how it effects horsepower and track times.
So he told me he was raising fuel pressure past 65 psi to see what would happen, well truck ran sluggish and slowed in track times. So he went the other way and truck kept getting faster and faster, he stopped at 45psi, regulated return.He told me trust him and try it, well since I had my regulated return set for 65-67psi I tried it. Well geuss what it worked I lowered to 50 psi and dam, truck felt stronger and quicker. Egt's also dropped 100-150 degrees, I know this makes no sense but it works, my fuel mieage increased abou 2-3 mpg.
Since it worked fopr me I told Nate(windrunner408) well it worked for him to all of it. So I past the info to Chris (strokin 6L) and worked for him, but can't say anything about mpg.
I talked to my injector build and he told me dropping psi to 50 or even 45psi, will not hurt the injectors at all, I still feel better at 50psi tho. International says that 44 min for fuel pressure so I guess they do know their engines.
So basically what I'm saying is if you have a regulated fuel system turn it down to 50 psi and you will see a differance, and if you do get on this thread and tell everyone. Any info I find that works and doesn't hurt truck I will always share, just to make the 6.0's better. So trust me on this and try it, I know it sounds nuts but it does work. It works great for bigger than stock injector and stock.
