what's up Todd. I saw there haven't been any posts here so I thought I'd say hi.
For those who do know, Todd is the go too man for modded
CR rails. Many are very skeptical about this mod but, there is also 100's of trucks out there running them.
When there's more fuel in the tank ( rail ), there's more fuel to dump into the injectors. There's also more fuel to dampen the pulse from the CP3.
I've ran his extreme rail for well over a year now without issue. Every little mod can help increase power and some also help longevity. I believe this to be one.
Check out Todd's site for more info or call him.... he's a cool dude and loves to talk truck !
