Hey Steve, thanks for your response. I tried this and didn’t notice any change. I’m going to try to check for boost leaks now that you mention a leak here would not feed the afc correctly. It got me thinking what if there was a leak preventing boost being built before it hits the manifold?Been awhile.
Back to the supply line, if the waste gate diaphragm is ruptured and losing air pressure and it is TEEd to the AFC line there is a good chance the AFC is not seeing a lot of boost and not fuelling up and therefore low power with no smoke. Either change the waste gate actuator or plug the line going to it and see how it drives.
