Default Boost issues after external wastegate

Im having boost issues now where im only getting base boost.

- Not the wastegate- Hooked direct pressure line and it will boost uncontrollable. Knock light works well.

- Apc solenoid functions. Clicks on start up and when brake is hit. Air flows accordingly through ports. When APC is unplugged with car ignition on the solenoid clicks.

So with that said it leaves suspect to the pressure transducer under the knee bolster. How do I check to see if it functions properly?
