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.

Where is the map sensor, how can it be checked? Under car, What's red rubber band i see dangling, where does it go, could that be problem? Thanks.

Can the wastegate nut be tightened from underneath car or is there removal of stuff?

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

Map sensors are in the intake manifold and the other on the lower charge pipe

Map sensors are clean and connected. Can wastegate be tighten from underneath car?

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.
