Same problems occurred in both logs. Acts differently. Sometimes boost switches off during pull, sometimes it switches off after pull. F.E - during pull - OK - after pull, if you do pull again, boost is cut. CEL ON - No Drivetrain Malfunction. Tried 38psi target. 35Psi actual. Adjusted with wg position but problem was same. (Tried just to make little deviation to not be near overboost area.)
