i currently just installed a defi boost gauge racer series on my 2013 wry
i noticed that the t fitting was nice and snug with the hose that came with the gauge but the hose to the bpv is bigger than the t fitting. currently i have them zip tied. I do not believe i have a boost leak cuz i hear no whistling sounds. at wot it hits at around 15 but then it dips to around 12. *from what i've read thats normal)
i do see people talking about brass t fitting. i want to know which one i need to buy. Thank you.
