Question

Quizplus · Accepted Answer

Technician A is correct because Variable Geometry Turbochargers (VGT) can adjust the flow of exhaust gases to reduce turbo lag. Technician B is also correct because VGTs can create more exhaust backpressure due to their design, which can restrict exhaust flow at certain settings.
