BOV for Stage 3 KC Turbo a good idea?

I mounted my stage 3 KC turbo a couple weeks ago which is just awesome, even with stock injectors and whistles so LOUD but I'll save that for another thread to keep this short. Anyway, last week, my stock radiator cracked, leaving me stranded on the side of the road so I had the truck towed to a local Diesel Performance shop - Diesel Unlimited located in Alabaster, AL...they did my head studs and bunch of other stuff few months back. They're quick and do great work.... I've got an aluminum mishimoto radiator on the way and decided to just go ahead and have my 190/75 warren diesel injectors and WPE race ported manifold that's been sitting in my garage for the last 2 months installed at the same time. I didn't feel comfortable trying to tackle that myself or doing the manifold. While there I'm also going to upgrade the fuel system a bit (that part I'm still trying to decide what exactly to do) basically trying to knock everything out at once.

So the main question here...I'm sure everyone has experienced "turbo fart" at some point on their factory turbo and I'm just curious would it be a good idea to look into adding a blow off valve on my truck to release pressure now that I'll be running a bit more boost with this larger turbo? I know that on a stock turbo it isn't necessary but i've read that when you start running more boost all that pressure going back out through the turbo could cause damage (and I think bovs sound awesome)

Just curious if its something worth looking into or not. This truck will continue to be my daily driver and I like to beat on it pretty often so I'm just trying to keep the motor happy.

That stage 3 is still a VGT correct? If yes, then if it's working correctly, you shouldn't have "turbo fart". You don't use BOV on VGT. Not that I'm aware of anyways, unless there is she new fad I'm clueless about...

Tuning is usually all that is required. The "chug chug chug" usually happens when letting off the throttle suddenly during a really hard run. Flow drops and pressure is too high and you get a turbo fart. This will also happen if not running custom tunes made for larger turbos.

Try tuning and see what you figure out.

Yeah it's still VGT, and I have a tune specifically for that turbo but I've noticed it a couple times. If it's not something to really worry about then good.

Damn BOV kits for our trucks are just stupid expensive for whatever reason so Id rather save my money to beef up the trans that will probably break sooner rather than later.
