Having a non stop issue that started occurring after changing nothing on my set up. ST have a old vrsf charge pipe and in between shifts the charge pipe would pop off the throttle body occasionally under full boost. It started happening more frequently and now all the time I hit boost. I’ve changed the o ring with a factory one and the clip and still same issue. Its Absolutely seated with the clip all the way around the throttle body.

Is it more likely the charge pipe has worn from vibration overtime?I don’t see any abnormal wear on the throttle body and if it was only in between shift I would question my BOV not responding fast enough but it’s as soon as I spool up. Ideas?

There is no amount of boost pressure that will force those clips outward. This must be related to the engine flexing or something like that?

What motor mounts do you have.
