kewl, do u have the mods to support that much fuel ?

u know fuel = heat .. with out more air flow your gonna heat the pistons up real quick and smoke like a freight train .. and get pulled over possibly and fined heavily .. Stock would actually have been fine and once you get the bugs worked out .. go from there.

Ya I know its a little heavy on the fuel side but i have a boost elbow on the hx35 and 4in exhaust all the way back and a high flow intake. I have a good set of gauges and always watch the pyro, shes always ran very cool, ill be sure to keep my foot out of it until i get a turbo pushing some more air

Heres the link for the AFC tuner Dodge Ram Cummins - 1994-1998 5.9L 12 Valve Dodge Cummins - 12 Valve P7100 Tuner - Diesel Auto Power, LLC , Its a little spendy tho . Anyways I put the new injectors in and bled the air out. Same problems... Runs great above 1500 and starts to fall off anything below that. I can blip the throttle and keep it running down to about 1000rpm, below that she dies quick. still wont start without a shot of ether either. Sounds like its definitely time to check the timing right? Im all out of other ideas, Its getting around 25psi to the IP which is stock spec. Any other thoughts?

timing is super easy ...

turn engine over, have one person get the pin into Ip..

pull the Ip gear off, turn engine backwards till its pinned, put Ip gear back on... in a nut shell that's my understanding of factory timing ...

Does it seem to get worse the longer you run the truck? I am having the same problem with my '96. If I run a couple hundred miles straight, stop for gas, and shut the truck off it seems to start way harder than when I started it cold.
