I will be replacing vac lines tomorrow as I haven’t done them as the second owner of the car and I don’t think the first owner has either. I’ll check my DV and charge pipe connections as I’ve blown my charge pipe coupler clean off the pipe before. I’m hoping it’s just a vac line to a wastegate that’s splitting. Once vac lines are swapped and I check all the connections, if it’s still happening I’ll see if I can vac test my solenoids. Is there any way to test them without a vac tool? I would like to avoid buying one if possible
Not really sure how else to test them to be honest.

I hope you already have a Metal charge pipe, stock ones will eventually crack/blow especially when you are tuned.

Wastegates could also be playing up, if they aren't staying shut properly etc, but do one thing at a time to rule them out.
