This is a 2 litre turbo Zetec I built many years ago. The rough starting was due to it a) being a brand new calibration and b) the starter motor was causing some electrical noise resulting in the ECU re-setting itself randomly on crank. It made just over 300bhp on the Dyno before a small crack was discovered around one of the spark plugs in the head. This didn't affect the running of the engine at all but the mapping wasn't able to be 100% completed. Even though, this engine produced over 300 ft-lb of torque from 2700-6000rpm. The engine was stripped down and checked, all OK and a brand new head installed. No longer required for the project, this engine was sold on.
