Sounds about right to me. I had my SRT version dyno'd two weeks ago and the print gave wheels and engine values, as the 'coast down' measures the drive train losses and adds them to the measured wheels bhp to interpret the engine power.
Mine is standard and gave 280.2 bhp at the wheels, 333.0 bhp engine with 305.0 lbft torque, giving 53 bhp drive train losses. Although mine is an SRT I would not expect a significant difference in gearbox and drive train making yours sound pretty good.
