Not sure if I may have a problem or not but it seems my rail pressure has dropped at idle. With the TNT rp set at 3 the past couple weeks I have seen my idle pressure at 7500psi, now recently it idles at 5000psi. Other than that truck runs the same , just curious if this could be an indication of something on its way out, plugged filters or just normal for it to change. Any insight would help.
Thanks

 

mine has always idled at that number ever since having a gauge. that was stock pump, and now the stage 3 pump.stock injectors

 

mine idles at 8000-8200 without tuning but with pump its around 6000

 

03 and 04 trucks should be around 5400 psi, 04.5 and newers are around 6800

 

Thanks for the input like I said not sure if I have a problem but seeing 2500psi less than before has got me concerned.

 

Mine has done the same thing. Last time it changed I unplugged my RP gauge and plugged it back in. Problem solved.

 

Thanks Spooler will give that a try tomorrow, if that does not work I will change my 2 micron filter and go from there.

 

is it cold there,when its below 0 here i notice a lower rail pres too,mine idles at 5300 and when its below 0 it idles at 48ish,i was told this is normal for cold temps,could be hapinging wwith urs too,
