2009 cab and chassis smoke after new turbo.

[Boogerbear]

Hello, I am completely new to forums of any kind but I'm reaching out for some suggestions on my 2009 cab and chassis 3500 with 375000 miles and completely stock. I have basic mechanical skills and try to fix my vehicles myself but electrical issues get the best of me. I know it might be lengthy but I will give as much info as I can.
Last fall I went to Ohio from Minnesota and noticed it started blowing black smoke. It threw codes p0101, and u010c. I continued my journey there and back where I parked the truck for the winter. It sat all winter. Upon starting it this spring it would barely make it down the driveway blowing excessive amounts of black smoke. Once I got on the county road it "cleared up". I decided to put a new turbo on that i got from Genos. I installed the new turbo and had the truck deleted. Now comes my issue. While driving about 10 mph it lopes and blows puffs of black smoke, and under medium to hard acceleration at 60 mph the turbo make a popping sound and you can feel the truck "surge" as the turbo kicks in and out. After that happens the exaust brake quits working. I cleaned the back pressure tube, installed a new fuel filter, and put in a new fca from genos. After i shut the truck off and restart it the exaust brake works again. The turbo side of the engine seems to be very hot, hotter than normal after this happens. My scan tool shows the vgt position moving from about 4% to 85%. I cannot read the commanded position with my scanner. No codes are present. I just want the truck to run normal and stock.
Any thoughts on any direction I should look would be very much appreciated before I bring it to the local shop for help. I enjoy reading the tdr and read it cover to cover.
Thank you very much in advance for any suggestions.

Did you spend any time with the truck and new turbo before installing the delete tune? I wonder if it didn’t upload properly or it’s a poor quality tune. It does seem turbo related like the veins are cycling open/closed when they shouldn’t be.

 

[Boogerbear]

No I didn't, just driving it for an hour or so and seemed fine. After talking with the guy that did the tune he said the tune was not related at all. I find it hard to believe, but maybe it's coincidence? I don't t know anything on how tunes work but a local shop said they could retune it. Im regretting deleting it at this point.

Just throwing darts here, what about the injectors? And is the "tune" causing a rich or lean issue?

 

[Boogerbear]

My gut tells me it's the tune. It's too coincidental. I was just seeing if anyone has run into an issue like this and could be something I'm overlooking.

Sounds to me like it could well be a sticking vane actuator.

It would be helpful to know which turbo you bought from Genos and if it came with the actuator already calibrated.

 

[Boogerbear]

It came with the new city diesel actuator. I was told there is no calibration needed.

Can you reflash the factory tune yourself? If you can I imagine the cel will pop because many things are no longer connected but maybe it will let you test drive to see if it drives normal. Just a thought, not sure if great idea or not….

 

[Boogerbear]

No I cannot. Im going to have the local shop look at it next week, they have more advanced tools than I do.

Check everything associated with the air ways for restrictions, beginning at the air filter all the way to the tail pipe.

If you have black smoke just rolling down the main street it is very unlikely the Turbo because you don't have boost at all then.
Only if the vanes would be stuck shut could cause a restriction then.

And now with the delete it is a total black box, no one knows how much they changed with the programming. Factory it would throw codes for sure with these symptoms.

Why it was deleted after 375k trouble free miles stays a riddle to me..

 

[Boogerbear]

Thank you for the responses. I will check the system this weekend. As for the delete I got tired of cleaning it and jumped the gun on deleting. A night in the garage wrenching every now and again isn't bad. I regret deleting at this point.

If I recall the 2009 ecu had extra security and there was a program that was loaded before the efi-live tune was loaded to open the gateway. You may want to check your tune writer to see if they accounted for this. I only run on stock power setting and the truck runs so much better.

 

[Boogerbear]

OK, thank you very much for the information.

 

[Boogerbear]

Turns out it was the tune. All is well now.
Thank you to everyone that responded.
