What should I do about this? Turbo related.

[kilr4d]

My rig is a 2006 C/C 4x4, 33" rubber on 20's, EGR delete, ELC coolant, MBRP exhaust, running an unlimited tow tune. Rotella T6 every 6K miles. Truck has 105K miles. About 10K miles ago I got the FICM and all 6 injectors replaced as a last kick at the can with the Ford warranty.

Took a 6 hour highway drive this weekend and got a hand calc'd 16.2mpg, not towing. On the way home, I towed a tandem axle car trailer with a 1956 Ford and some spare parts...probably a 6K - 7K trailer weight. ran fine for the first hour, but when I started pulling some grades, I got the P0299 code and the wrench icon. Cleared the code with my SCT a couple of times and the wrench icon cleared itself everytime I stopped the vehicle. Power was down and shifting was sluggish while the wrench icon was on.

Now that I'm not towing, neither DTC has come back and the truck seems to be driving reasonably well. I haven't had a chance to hand calc another tank, but *** of the pants I think the fuel economy is still off a bit.

So....do I:

1. Disassemble turbo and clean via the DTS article?
2. Rebuild turbo with stock components?
3. Rebuild with batmowheel?
4. Powermax?
5. Other?
6. Forget this happened and move on?

Thanks for any help and suggestions,

John

Here's my opinion of each of your solutions, take it for what its worth:

1) Good starting point, if funds are tight.
2) I wouldn't waste the time with the options on the market that are available.
3) Batmowheel will not fit the '04.5-'07 turbos, won't see anything to correct this issue
4) Good option, but there is a better option I'll address regarding choice 5.
5) Take a look on here at the Mad Turbo Werks units, plenty of threads on what he's doing with the 6.0L turbos.
--Stage 1, runs about $700 + core (or send your unit in) and is a good stepping stone turbo that will improve performance and fuel economy.
--Hybrid, runs about $1200 +core (same cost as a Powermax). This turbo is just starting to be built, and will include a batmowheel at that cost. This is the primary turbo I'm looking to install later this year, and should run better in the '06 than a Pmax drop in.
--Stage 2, if you are looking for a little more out of it.
6) This is definately worth correcting.

Any questions, let me know.

Use a better code reader than the SCT, it is not good for reading codes.


Check your CAC boots, and the flex joints on the exhaust up-pipe and y-pipe.

What were your coolant and oil temps?

Interesting. I've sent him a pm asking him to chime in this thread.

What is wrong with using an SCT to read/clear a code?

CAC boots and flex joints all appear to be ok.

I don't have an Insite to monitor oil temps...I hadn't bothered since I did an EGR delete and coolant flush.

Coolant temps on the SCT were 196F in the flats and 204F pulling a hill.

The EGR deletion does not eliminate the need for a monitor on the 6.0L. Its a band-aid solution for the Oil Cooler failing. Not rebuilding/replacing it when required with a deletion, could lead to a rupture into the coolant system. I strongly recommend you get a monitor like the Insight and keep a better eye on things.

The monitor can help diagnose and prevent a number of other issues, and I have a link to a thread covering those in my signature.

You would have indications of MAF, VGT duty cycle, and Boost levels on the Insight that would help you diagnose your turbo issue for example.

SCT can only read basic codes (generic), you may have other codes stored that the SCT can't read.

You asked about your ECT/EOT delta, if you have a newer PCM strategy, the "wrench light" will turn on if your ECT/EOT delta is too much of a spread (P012F code).
