Who can tune this thing right?!

The reason we need VGT turbo here and you need a fixed vane there is the engine loads. Over there you guys pull heavy and require high engine loads the majority of the time. Here we see an average of 30% engine load so we don't need all that air being rammed into our intakes. We require varying amounts of air here and the VGT gives us better low end response a d a more powerful engine brake than a US truck without one.
