RAIL PRESSURE!?!?
 

Need insight on my 07 32500 5.9 6spd fuel rail pressure... @ idle it seems to be right in the mix of normal being between 6-7k... that bein said cruising at around 60mph/1800rpm it stays steady around 20k... ANY increase of throttle and she drops to about 17-18k or a little lower untill my foot levels out... am i where i need to be or does this seem off!?:humm:

opions and inputs of any kind would be awesome!!:c:

proud 3rd gen CR owner...

It sounds about right to me. I would keep an eye on the pressure and if it really starts dropping then you could have an issue stating.

so normal!? trucks basically stock except for 4" stright, K&N cool air, and BD boost fooler...
on another note... any knowledge on boost psi at the top of any gear?? avg??:choochoo:

yea, sounds normal to me
as for the boost pressures, sorry, I don't know.

ur posted in the 12 valve area.about a CR ......... have u posted this in thd 07 area .... more guys might have more info on these because they own one ... just askin ?:tu:

yeah posted it in the 03-07 but figured more would see the post if i hit it up on the general posts.. thanks:c:

was gonna say...this isn't the 12v area....

Your pressures seem alright. but I'm not a CR guy either, so I'm not 100%

if you have stock injectors, chances are you won't be able to pull your rail pressures dangerously low even with an aggressive programmer...

usually takes aftermarket injectors to create a need for an upgraded/twin CP3 pump setup.

however upgraded lift pump never hurts as the stock lift pumps can't keep up with aftermarket mods on any generation truck.


also throw the K&N filter in the trash and replace it with a quality dry filter...

oiled air filters + high boost capable forced induction engines = a no no...

the turbo can suck hard enough on the filter to pull the oil right out of the filter gumming the compressor up and allowing dirt through..
