Blow Off Valve Upgrade? Is It Even Necessary?

Just wanted to draft this up now that I’ve got the Cali Raised 32" Dual Row 5D Optic OSRAM light bar installed in my Stealth Bumper. The fit was perfect, brackets lined up exactly where they should and it sits clean and flush behind the bumper opening. Couldn’t ask for a better match. I wired it into the factory aux switches and it works flawlessly. Everything powers up smooth and it’s nice having it tied into the truck without adding any extra switches. If you want to see how I did it, here’s my post on wiring to the factory aux setup: Factory Aux Switch Write-Up The light output is wild. It throws a ton of light down the road while still spreading wide enough to cover everything in front of the truck. This will quite literally turn night to day.

So to my knowledge, the new turbo motors have a blow off valve (BOV). Correct me if I'm wrong. I think the only design alternative is a bypass valve (BPV). Just something I learned while doing some research.

Has anyone seen any upgrades for the 4th Gen? Is it even necessary, or possible, etc.? I can't see why the motor wouldn't benefit, given the reported positive impacts that I've heard it brings. I just haven't seen anyone say anything, but I understand since the motors are newer.

Let me know! Post any links if you find them.
