How do you check turbo boost?
Checking turbo boost pressure
This is best done using a vacuum/pressure gauge but can be monitored on your scan tool. If boost pressure is low, check the air flow corresponds. If the air flow is higher than boost pressure indicates, then suspect a leak in the induction tract.
How do you know if your turbo is weak?

What controls the boost on a turbo?
It's the wastegate's bypass valve that controls exhaust gas flow, which, in turn, determines boost pressure. Here, a small flapper valve located inside the turbine housing opens and closes, determining exhaust gas volume and, ultimately, managing boost.
Does a turbo need a wastegate?
The wastegated turbo is great because it's got a housing on the exhaust side that will spool that turbo up quick, but at the high rpm, when it's spinning fast, it's just too much for the compressor wheel. So, we need a wastegate to control the speed of the turbocharger.
What is normal turbo boost pressure?
What Is Normal Turbo Boost Pressure? Approximately 6 to 8 pounds per square inch (psi) are typically provided by turbochargers. The normal atmospheric pressure is 14 on a hot day. At sea level, you can measure the extra pressure that the engine receives by approximately 50 percent.
