P0299 code - Turbo under boost.

So got this code and only producing 5psi or less. So I'm guessing I have a leak somewhere, anybody have pictures or diagrams where possible things are to look at? Where is waste gate located and how to access my he things I should be looking for. Thanks in advance to any help.

Either a boost leak, or a failing or dirty map sensor.

What is this? Find that out first before you go messing with the wastegate.

Qfe, don't go tweeking the wastegate at the first sign of low boost. Bad things happen.

Okay, thank you. I'm just going totally clueless of what this problem is. Everything looks good, map sensor is clean. Car runs totally fine besides 5 psi boost and p0299 code.
