Ac wire was a bust. Little bit of rub on the tubing but nothing into the wire. Will check them ecm plugs this weekend

As far as reseting the duty cycle im assuming it just resets them to a pre determined point fixed in the programming then adjusts them from there to the how the truck runs

I have looked and dont think there is a contribution test for my year, unless the DRB3 at my work is that out if date. Will try disconnecting the fan and see what that does and if nothing i will check the ac connector and the ecm connectors. Is it the actual Ac compressor connector or the high...

I used brand new bosch injectors from a local cummins mechanic who has been buying from the same place for years. As far as idle i do have a tach and i have tested the cluster and the self test passes. I have watched the ecm readings with a drb3 and i cant see anything unusual the map readings...

Also when shifting through the gears sometimes mostly lower gears. When getting closer to 2k it power spikes. I dont notice a jump in rpms either. Feels like im stomping the pedal before i shift

Okay so here is the list 03 6 speed, new injectors as of a week ago with new updated crossover tubes. FCA replaced about a year ago. Rail pressure sensor and pressure relief valve changed a couple months ago. All new high pressure lines, Fass 95 with new fuel filters about a month ago. New ats...

UPDATE: swapped a new turbo in. Power is back and ticking is gone.

looking to get rid of my sloppy he341 for a he351 but im not looking to break the wallet. Looking for a good take off with no play if possible. Let me know!

I see what you mean. Noise doesnt happen at idle. Idle is normal and smooth. The ticking only occurs through the rpm range. Usually starts at about 1100-1200 and up but goes away if you hard in it. Also does seem to occur more with boost. Only ticks with light throttle that i can hear but its...

The injector return flow spec is 180, i was just saying mine is 80ml. I havent looked at contributions yet. The DRB at work doesnt show cylinder contributions for 2003. Injectors were remans through an approved bosch dealer. Valve cover has been pulled. Nothing looks abnormal and valve lash is...

Boost is maybe a pound lower at wide open. No codes other then lift pump circuit high cause its unplugged

i have a 03 5.9 6 speed. The truck is completely bone stock other then a fuel system and an exhaust. Recently the truck has been down on power intermittently. It has good fuel to the cp3. The injector return flow is more then below spec, about 80ml in a minute. The rail pressure relief valve is...
