P00AF — Turbocharger/Supercharger Boost Control "A" Module Performance
Limp Mode On Grade

This vehicle has a new vgt actuator and is not matching commanded vgt position up a steep grade after turbo has reached 1200 f . I then go into a limp mode and have a vgt actuator that does not move until a code clear . It defaults to I believe the halfway point causing poor boost . The video is this same turbo . We will next replace entire turbo . Any thoughts ?

You can try relearn turbo position sensor or reset KAM memory
