When you run the rails dry it puts a lot of stress on the injection pump (cp4) which can burn it out and send metal down th fuel rails and to the injectors. A couple guys on the DF did it and repairs were in the ballpark of 10k. id get that lift pump ASAP

I have ppei tunes I have it on the eco tow tune.. I've read it's the 60hp tune but I've also read where some people say it's the 120hp tune but I don't think that's true

yeah add a lift pump and see if it still does it.

if it does still do it take some data loges and send them over to kory he'll take care of you.
 
Why don't you data log before throwing money at it. Imo you'll need a lift pump anyway with shitty cp4, but a clogged filter WILL do the exact same thing.

I plan on doing a data log once I figure out how. Will I be able to do one even tho I have a apple computer?
 
I have just over 9k miles do you think I already need a new filter? I planned on doing it at 10k
 
No efi live doesn't work with Mac I'm pretty sure.. And yea dude I change mine every 5k and mine was loosing rail pressure from a clogged filter...
