A method and control system for manufacturing externally enhanced evaporator tubes. A pressure signal indicative of the pore size on the external surface of the enhanced evaporator tube is provided to a microcomputer system which processes the signal indicative of the pore size and compares the signal to a predetermined pore size signal to determine when the pore size is within a selected tolerance. The microcomputer generates a control signal to adjust the enhancing process if the microcomputer system determines that the pore size of the manufactured tube is different than the selected pore size.
