Boost Cut And Jaults?

[triston]

Hey all just asking a question about my 33, ( hope im in right section ), anyways i have a 33 and when i fulll boost it to 7 psi sometimes it jaults and boost goes down, this mainly happens in gear 3 when i reach 7psi after about 1 second ? i looked at all the bov pipings and one of them to from the bov to the main block its a little cracked on the bov end ? would this be the reason ? should i just change that black tubing? thanks. anyhelp will be appreciated.

Sounds like a boost leak, the higher boost opens the crack up and becomes a leak
