That right there. You need to familiarize yourself with the turbo. You didn't replace the wastegate, you replaced the actuator. At least that's what you said you did in another thread you started regarding low boost. You need to see if the waste gate arm will move, they rust, it happens, and if it's stuck open, you won't build much boost, and won't get any fuel due to the afc limiting it until it sees boost.
