05 LLY is throwing a P1093, we put a race valve in it and have changed the fuel filter and it is still throwing it. Would a lift pump help or do I need to start looking at injector wiring?
Thanks, Cody

when is throwing the codes, what kind of tune you running? huge tune a lift pump would help that. if its a bad cp3 the lift pump wont help.
yes lift pump should solve the problem....
also be sure the race valve is super tight. if not they can leak

It just has a bully dog tune on tow and thats it. It happens as soon as you get on it at about 40-50 mph it just falls on its face.
Do a bottle test. To make sure the race valve is working

sometimes the shim is better than the race valve, a lift pump should help, but I wouldn't think it necessary on a tow tune. Try the bottle test, probably the best place to start.

not sure on specifics of bully dogs, but i doubt they are using enough fuel in tow to drain a rail like that. its either a leaking valve like kat said or a bad pump/regulator.
you might try a different setting on the bullydog and/or put it back to stock and see if the problem persists.
