Question Any recommended free mods? ZooDad done

[Choaner]

Thanks for any help, just curious what I can do before spending Much/alot.. Plan on getting an MBRP 4" soon, any help to removing stock cat/muffler? Hear about some fuel pressure increases.. Worth anything?

Thanks for any help.. Great truck so far - rotated tires couple days ago, took a good hour to un freeze wheels from rear hubs..

There is not much you can do for free or even close to it. Playing with the fuel pressure is not a good idea. Bigger injectors will give you more fuel. They are big $$$.

Dave, you don't doing the Blue Spring mod is a good ideal on a 6.0?

Never heard of the Blue Spring mod.

Harpoon the fuel tank. Ford upgraded the fuel pressure regulator spring, it's got a blue coating. Hence the "blue spring" upgrade....

Ford updated the fuel filters...some say they restrict flow so Ford had to change the regulator spring as well.

Free mods are few and far ....I suggest you drive it and enjoy it. 6.0s hate to sit in the driveway.

Check your EGR valve. If it needs it clean it. Not free since you will probably need to get new gaskets for when you put it back. A good look will also help you have some idea about health of your EGR system.
