Anyone know what anything about it???? I'm considering it now since I'm running the Smarty Revo. The Revo increases rail pressure. I've got the Revo on the default settings which are supposed to be safe for stock injectors; but I just want to know what's going on under the hood!!! :smart I've got an Edge Juice w/Attitude for sale if anyone is interested!! I had it on my 04.5!! Works well!! :thumbsup

I would say get the gauges before you turn it up much so you don't pop something... http://www.danininc.com/optix/gauge/200140.htm

Got this Quad rail gauge installed on Thursday. From my research regarding rail pressure, my truck is right where it should be at idle and cruising for 04.5 and up 5.9's. About 6500psi at idle and 15,000-17,000psi cruising 55-60 over fairly level roads. Haven't done any WOT tests yet. Even the way I have the Smarty set with a bit more rail pressure, these are normal numbers. :smart

From talking to guys over at TDG.com I found that 27K is about your limit without blowin' up your injectors...But 6K to 7K is about right for idle... ;)
