Good day, first post here so please be nice

I have a 2018 FiST, previous owner did some mods, Turbosmart BOV was one of them, driving on the highway and hear a pop, no more turbo flutter just whooshing and my access post says I’m making at most 6 psi, was pushing almost 27 before, checked the BOV and the cap popped off, screwed it back on but I’m still only making 12 psi and still no flutter, any idea what I should check next?

They looked good while I was under there, I’ll take a better look next time I’ve got the car up

That sounds like wastegate pressure - you should check the vacuum lines running to the wastegate and/or wastegate (boost control) solenoid

Thanks everyone, the blowoff valve failed and the whole piston and spring ejected themselves, working on a warranty claim. Thanks for all the help

Symposer port BOV is awesome. Makes cleaning a breeze
