2012 6.7 intercooler upper pipe explosion

Yesterday I had my Egr and Dpf pipe deleted and added a tuner. First thing I noticed was I could hear the turbo. Odd enough something sounded off. Well I couldnt hear it so well in the cab but my friend said he heard it as I left work. There was an underpass on my way home sound figured Id see if I could hear it under there. Boom! Suddenly I lost psi but no engine lights. I pulled over to check under the hood and find this obliterated pipe. The piece I am holding in my hand was laying just behind the throttle body. So i believe everything is fine my only concern is any pieces possibly be in the line of fire of that turbo and ultimately getting sucked in! I have already ordered a lower and upper replacement pipes. They are not plastic (for whatever reason Ford engineers thought it was brilliant to make these this way). From what I have read up online this pipe is a ticking time bomb and explodes when it wants to anytime no matter what. We believe it was already cracked hence the funny sound. Input and suggestions? I am trying to figure a course of action to take with this.

You've already ordered an aftermarket replacement? That's the correct course of action to take.

Yes sir! I ordered an AFE BLADERUNNER 3" INTERCOOLER HOT AND COLD SIDE TUBES kit. My only worry is this explosion of plastic parts ruining my my turbo, engine, or both. Should I worry?

No. The the tubes are after the output of the turbo. Doubt any engine damage.

Usually only need the cold air as the stock Ford hot side tube is metal.

Very likely it was cracked. When the clamp areas were cracked on mine I was down 3 PSI and could hear the hiss from escaping air.

I replaced mine without it being broke around twenty some thousand miles with a Rudy's kit like this. The stock hot pipe is metal already. Here is a link to Just Strokin's thread for install.

Yep, very common indeed. Replace the cold side with aftermarket and you're good...

Here's my thread on it. https://www.ford-trucks.com/forums/1...f-buffalo.html

I had the same. Issue today, put a new one on and now I am showing about 38 psi on gauge when I turn on the key. I start it and then kill it it goes to zero. Start it back up and my turbo is very sluggish for the first few miles then it runs the normal pressure but still feels off. Any ideas?

Failed MAP sensor.

What does the map sensor have to do with the turbo pressure gauge? The 38ish psi was showing on the turbo gauge with and without the truck running. What are the odds of map sensor going out the same time the intercooler pipe explodes?

I agree it is odd this also failed but it's one of the sensors used to calculate a boost gauge reading to you on these trucks. When the MAP sensor has become damaged or failed, the ECM typically defaults the boost reading to 37 PSI.

When mine had this issue, the gauge was stuck at 37 PSI at KOEO and KOER with DTC P0107. Additionally, the engine sounded like the exhaust system was plugged up (best way I can describe it), exhaust was entering the cab (I struggled to make it around my neighborhood when testing) and it had a significant lack of power. I replaced the MAP sensor which immediately resolved the issues I listed.

Someone who understands turbochargers can better explain how the ECM calculates boost (MAP, EBP, BARO). I am not much of a fan of throwing parts at things so I recommend gathering more information where you can. It's an expensive sensor at the dealer.

Thank you so much for the explanation. I know enough about diesels to get myself in trouble. But I am learning. Very appreciated.
