A powertrain optimization device and method that compares a predicted performance of customer-selected vehicle components to a customer-selected optimization goal. A method is also provided which includes the steps of supplying compressed air to the combustor from the integral compressor; and supplying at least a portion of the cooling air or other cooling media to the hot gas path parts in the turbine component from an external compressor. A result of M antenna diversity may be achieved for M transmit antennas.
