I'm curious what we are to make of the efficiency increase with the initial round of aeromods, before the kammback and tail were added. 15% improvement with wheel covers, grill blocks, mirror delete, etc; then the tail did hardly anything. Is it possible Metro just happened to hit a plateau in engine efficiency?
