    Hi guys, i replce the exhaust manifold and now when i put all back together, after driving for around 5 miles i noted that the truck lose power. When i put the computer it has this active code:
    Variable geometryc turbocharger actuator #1 Mechanical system not responding properly. Code SID 27.
    I start the truck and the code goes inactive and active, intermittently at intervals of about 10 seconds.
    Maybe a loose wire?
    Maybe i didn't connect the plugs to the right one u know what i mean?
    If it was connected wrong does it ruin the vgt?
    Any advice please?

    Thank y'all.. blessings!!!

    Did you separate VGT from the turbo? If so than VGT needs to be installed in a specific position than needs to be calibrated.
