Carbon build up in turbo leading to bad lag?

[louidoui]

I know that the 6.0 has a natural lag, but mine is getting really bad. A good 4 seconds of coasting under 20, until I get real power. during all this time I get a decent amount of black smoke out of my exhaust, considering its stock. This all started happening after I took my programmer off. A superchip I bought when I knew nothing about tuning. I have been having more black smoke than I ever had before using this programmer. Taken it into ford and they can find nothing. Any help?

Yes, you might need your turbo unison ring cleaned. Excess soot from idling can cause problem with the turbo and EGR both. Rust is also a major factor in the unison ring sticking. This could also very likely be a programming issue.

So It looks like im gonna have to do that cleaning myself. Cause I can't exactly tell ford what I think is happening cause they know nothing about the programmer that was on and I still got warranty for another 100,000 kms. Have you ever opened up your turbo?

Cleaning a 6.0 turbo

Use the provided link. Your up pipe must be perfectly aligned BEFORE you install the clamp. The clamp WILL NOT pull the connectiion together. If you don't do this you WILL have a leak and reduced performance. This can be a real SOB, GOOD LUCK

Thanks very much, those are some great slides. Also you said excess idling can further ruin this problem? I have remote start and I have been idling my truck a good ten mins before I drive and a good 5 to 8 after work before I start driving and some in between when I'm stopped places. I guess I'll be limiting this to a couple minutes.

Also run cetane boost if the fuel and once a week drive it like you stole it to keep the egr valve and turbo clean and working.

You may want to get some new o-rings and clean the egr valve also

Currently running cetane booster, cleaned my egr valve about a month ago. I'm gonna try running er a bit hard and less idling. I noticed today that when I only let it run for a minute before I drove that the lag was way better. I think me idling it for ten minas every day before I drive has made this a lot worse.
