I have an 04 6.0. I have 190cc injectors with stock nozzles from warren diesel, an airdog 2 running at 70psi and an idp custom tune. When I am slowing down, the engine develops an erratic idle until im almost stopped. Just wondering if its ok or should i get it checked out asap. It runs better than before with these 190cc injectors than it did with stock and starts up without missing a beat when its cold. And i watch the injector pulse width on my edge cts and it is jumping anywhere frim .6 to .8 and then down to 0 and immediately back up. My buddy said he had a friend with an obs 7.3 with a super duty hpop and it did the same thing and it turned out to be just an overfueling issue or something like that

 

Did you get the tunes updated for your injectors? I would tell Eric, I bet tuning can fix it.

What's the rest of your fuel system or is that it? The regulator on the AD2 is doing nothing if that's the case, or are you feeding directly into the heads?

 

Yep. I got it tuned now and there is nothing stock left of the fuel system now. It's AN8 line from the airdog to the AN6 y fitting. Today I got a cylinder balance code for cylinder 8 and it went away after I shut off the truck and turned it back on so im thinkin its that injector

 

Very possible. Do you have the capability to run a contribution test?

Just out of my own curiosity, why stock nozzles on a 190? You still on a stock turbo?

 

I did get a test done and all injectors are good. So I called warren and found its just something thats associated with larger injectors. And I got stock nozzles mainly because of money and I'm not looking to go insane with it yet. And yeah im on a stock turbo yet. But a powermax is in the future.

 

I know I've heard with large injectors and the truck in park or neutral if you try revving it up it will break up and sound like crap, but they run fine when in drive etc. Just one of those things I guess.

 

Mine just hangs for a second and falls right back down to idle. I just emailed eric so hopefully he can fix everything.
