Cruising speed is dependant on a number of factors, Weight, Altitude, CoG, and more importantly where engineering set cruise thrust, she doesn't like being heavy with an aft CoG. Like most turbo props fly them as hard and as fast as you can for best fuel efficiency. For cruise the power levers sit in a detent and torque is set by the EEC (electronic engine control), with some variation at the fuel control unit. Best leave the ERP (engine rating panel) in climb mode for cruise, she'll cruise along at typically 265 knots.
Oh! and when she was built back in 1985, she was way ahead of her time and arguably still is.
