Default FUEL RAIL CODE

Hey everybody my 07 LBZ is throwing a low fuel rail pressure code. I ordered a ppe plug that increases the volume but not pressure but they sent me their race valve. I'm debating whether or not to put this race valve in or let them send me the right part. This is a daily driver/work truck/drag truck so is it worth it or will the rail pressure be to high. Any suggestions or advice is very much appreciated thanx and god bless

get a shim kit and a ported fitting instead, assuming you are having a p1093 code, i had the same issue, could be a dirty fuel filter too...

lbz should not have a problem with the p1093, theyre designed to run 26kpsi from factory.

it could be a bad filter

we have a stacked program right now and if u stay on it over 3 seconds the code pops. but my ? is should I run the valve or the fitting I ordered. I have the valve but I ordered the fitting. would fuel volume increase help or should i just use the valve?

well if you stack programs its already commanding a high enough psi, and then add a lrge pulewidth and even more rail pressure it probably wont be able to hold it

theyre both completly different components

you wont see any noticable or even a little gain with the ported valve ad you can do that yourself.

the rave valve ive been told leaks a little, and fwiw adding some shims does the same thing

what are you stacking. the p1093 can be caused by alot of things, tuning and mechanical prblems
