Technician A says that a wastegate is used on most turbocharger systems to limit and control boost pressures.

Explanation:

A wastegate is a device used to control the boost pressure of turbocharge systems. This is achieved by restricting the exhaust gases in the system due to the exhaust gases providing the required pressure in the turbocharged system.

A good importance of the wastegate is protection of the engine and the turbocharged system.
