Well, that normally isn't good enough honestly. Make or get a boost leak tester where you can actually put some pressure into the system and find leaks. I would put any amount of money you'll find one somewhere.

I know I sound like a broken record in a lot of these help threads but I know first hand how easy it is to spring a boost leak and how much of a pain in the ass they are. Maybe I've had unusually bad luck with breaking a couple seams in a quality FMIC, ripping high dollar silicone couplers, busting fuel injector seals, but I doubt that I'm the only one.
