    Anyone install the Turbosmart Kompact EM Plumb Back Blow Off Valves in a 3rd Gen hybrid? If so, experience any issues or problems afterwards?

    I have seen exactly one reference to someone who has given these a shot - https://youtu.be/hGpcxnqrTns?si=vsnFCwgat_wG376G
    And wouldn't you know it, Mr. Xiong Dao turned off the comments and said nothing else about it outside "Plug and play. You can hear it pretty good". So im guessing that he hasnt had any issues.

    After owning a few factory turbocharged MAF and a few self turbocharged MAP sensor motors using SSQV's and trumpet BOVs, the only/best reason I can think of putting these on is to prevent future issues with the plastic recirc valves that come with the truck. Plastic inevitably fatigues after so many heat cycles and will crack, leading to boost leak and making your turbo work harder than it needs to outside of its efficiency zone. The springs in aftermarket valves end up being a bit stiffer and tend to hold better under sustained high boost once the factory valves end up getting long in tooth and start getting leaky.
    IMO - unless you're addicted to the *vrooooommmmm PSSSSSSHHHHHHHHHHTT!* of turbos, which who isnt, i'd probably pass for now unless you're also going to install upgraded charge pipes and/or increase boost over factory, OR your truck is getting up there in the miles OR you've got money burning a hole in your pocket. On the factory recircs, there is a crevice by the mounting flange that would be the first place they start to crack once they get old.
    (I found someone's picture of their AFE charge pipe install and drew an arrow for reference.)tundr charge pipe.jpg

    So if you REALLY want an excuse to put them on outside of *PSSSSHT!*, you can use the "to prevent future issues with boost leak and turbo wear" as your reason, lol. (but we all know its because the *vrooom PSSSSHHHHHHHHT!* ;) ). But really, screw the haters. Do what you want because you want.
