I have a 2004 with the 235 hp Cali SO motor, and am wondering what the fuel rail pressures on compared to the 305/555 motor, and if they are less than the 305/555 motor which is approximately 26,500?? I read everywhere on these forums about the pressures on the 305/555 motors but have never seen any for the 235/460.
I realize this may be the wrong forum but am asking here as I am running the Edge EZ module, and want to make sure I am not running it on too high a level with out having a fuel rail pressure gauge.
Thanks for any info.

I think it's about the same especially if you have the EZ box. I used to run one on level 5 and blew out the pressure relief valve gasket from too high of sustained pressure. The SOs actually get a better gain from the boxes than the HOs.

 

Should of known you would have the answer
I run mine on level 4 but with all I read on these forums was never gutsy enough to run on Level 5 as heard it was hard on injectors so decided to not go any higher than 4.
I thought maybe the 235 SO motor might be less, and with me running on Level 4 I would still be in the "safe" zone if they run lower pressures but maybe not. I plan on getting a Quad race box soon anyway, so hopefully I will not have any problem before then.
All I know is when I put the EZ module box on it really woke up the dually especially with the 4:10 gears but after all I read on here I get a little nervous about fuel rail pressures, and is why I thought maybe I should go with the Quad race box after all the good things I have read as I can't afford to get an Edge Juice, or similar til I get my tranny done(auto).
Again thanks for the info.

You will like the Quad Race box!!!!
