Tell me more about this, do you know what settings?

Well it was previously posted that Smarty beta does 25k at WOT....and the Quad XZT added about 2000psi to my rail over my Bullydog....so 25+2...you are already at 27k.....and thats with a XZT not a Quad Race.
As for the exact truck, I don't know what settings he was on. He told me Smarty Beta and Quad Race and I about flipped. I asked him if he had a rail gauge and he wasn't even sure...he has a commander and quad box so i informed him he had a rail gauge. I asked him to watch it and let me know....27800psi!

Beta 4.4 Pressures Idle 9.5-10K Anytime the throtle was depressed it was in the 20K's and WOT 25K or so
Deer, Spearco dropped temps 100, install was a pita because they didnt send the right hardware. I STILL HAVE CRAZY EGTS!!!! when my truck is in overdrive. The smarty runs to hot grossing 30K

)Anyway, IMO the best benefit of the RP gauges is the real-time dynamic pressure monitoring of the fuel map they provide - makes for a great peephole into the combustion chamber!

At the dyno I ran the Quad Race on top of last April's Smarty SW, and RP as usual "pegged" at 27.5psi on the DiPricol... graphically speaking - the DLs and pressure boxes tend to increase the slope of the rail pressure curve over RPM on the fuel map topography. Due to the RP sensor's limitations, who knows what absolute maximums are generated at the injector tip, but it does make the Flux injectors a bit more desirable! (Don, IIRC, tests/certifies them to ~35K psi )

I dont get worried about high rail pressure,, (25 to 27k) it is how it gets there that worries me.... there has to be a ramping up to that pressure,, if it hits too hard,, especially down low that is where trouble brews. From what I understand the way that the smarty combats this is to run at a higher pressure during idle which then allows the engine some breathing room.
As for egt's, as xl8r said, dont get too paniced about temps, unless you are consistantly going over 1350 - 1400.

............................ I don't think Idling has a negative effect on the injectors provided you have long periods of use to keep the injectors clean. An 80 year old guy I know delivers trailers all over north america and he has well over 450k miles on his 04 Dually and he never turns it off unless it is going to be off for more than 6 hours. The only parts he has replaced on the truck are 3 water pumps. He will idle it all night if he's sleeping in the bunk he fabbed in the back seat. I was at the shop when he was getting the water pump replaced....it ran for 2 hours before the water pump was replaced he turned it off for 15minutes while my buddy replaced the pump and then he turned it back on and idled it for another hour of chatting. Its a 4wd 48re. The tranny is bone stock and the only mod is an AFE PG7.
Wow! 450K miles and he hardly ever turns it off. I'd be curious to look at the hour meter on his truck. These engines are amazing feats of engineering.
