Finding The Boost Leak

[Mr_Fielgood]

A real newbie post but I plan to do my first boost leak test.
Any tips?

Use soapy water in a spray bottle to find the smaller leaks. As you spray it on with the piping pressurized you'll see bubbles form and grow. Boom. Super quick and it cleans things in the process.

If your throttle body is stock, I guarantee it's leaking out the shaft seals. If the throttle body is hissing then the seals are shot. Also the injector seals are the 2nd most common source of a leak. Be sure to check where the injectors are seating in the manifold.
