6.7 BOV (Blow Off Valve) Anyone Installed One?

Reading a bunch of threads about losing the factory turbo after DPF and EGR delete. Has anyone installed an aftermarket BOV? If so what brand and can you post pics of the install?

BOV is on the intake side and only going to help with turbo surge which I do not believe is causing failure. I have been wrong before but the surge on these trucks isn't really there. That being said, I am not trying to steer you away from a BOV, just making sure you know what the benefits of one is as they aren't cheap

You would be looking for a waste gate to save the turbo.

On the 6.7 the egr is used to control turbo overspeed.
When the ecm detects high ebp the egr will be opened.
This can be seen on a scan tool when ebp is high at wot the maf will drop by 70 g/s and power drops. We don't see excessive black smoke because the fueling is maf based and the strategy has an equivelency ratio to limit smoke.

Tuning vendors to my knowledge have not defined this portiin of the strategy ye t.
It would be great if they did as turbo life may improve.

There was a thread on another forum where a member was experiencing this. He deleted his truck but did not unplug the egr. The ecm was doing it job and controlling turbo speed.

I suggest rather than unplugging the egr just let the ecm do its job.
On a race or off road deleted truck use the factory strategy to control turbo speed.

Just route the egr exit to the passenger fender.
It will be cool gas so any ducting is accepttable.

When you are at wot and see black smoke be the passenger window you will see it work.
This will also reduce egt's and assist with max power.
All while taking care not to overspeed the fragile turbo.

I would venture to say ford engineers had this all planned and removing the egr has removed the safety.

I have been advising our customers of this for a while.
Its unfortunate most of our customers have already lost the turbo.

I was just going to ask the same question. I just purchased my full delete parts today including the egr kit but would be good to know if it should be installed or not.

The hundreds of thousands 2011-2013 diesel superduty's sold, and we know of what maybe 20 turbo failures on this site. People get online and complain when stuff is broken. I've personally never seen anybody complain that there truck is running great. Also, I hav only replaced one turbo at the dealership for a failure. For what it's worth I feel is it a very isolated issue.
