Review on Efficient Performance Upgrade: Part# 1831383C92 GTP38 Turbo 22PSI Wastegate Actuator for 1999-2003 Ford F-250 F-350 Powerstroke 7.3L Engine 1831383C94 by Dan Olsen

As with all components, problems can also arise with the wastegate actuator. Over time, pressure and heat take their toll, which can weaken the spring. This can cause the wastegate to open earlier than it should, reducing boost and performance from your turbocharger. The membrane can also fail, causing the valve to no longer open. This can cause boost pressure to rise to the point of causing serious, catastrophic damage to your engine!
