BEFORE TUNING
Before carrying out an ECU remap, we recommend ensuring your Ford Focus ST225 is in good mechanical condition. The engine should be free from fault codes, boost leaks and ignition issues. We also recommend checking the turbocharger, intercooler, spark plugs, ignition coils, cooling system and servicing history before tuning.
SERVICING AND MAINTENANCE
Regular servicing is essential for maintaining the reliability and performance of your Focus ST225. We recommend using the correct quality engine oil, replacing filters when required and keeping up with scheduled maintenance. A well-maintained engine is better prepared to handle the increased power and torque delivered by an ECU remap.
EXHAUST UPGRADES
An upgraded exhaust system can help improve exhaust flow and enhance the five-cylinder engine’s sound. Depending on your goals, options may include sports downpipes, performance catalytic converters and cat-back exhaust systems. Supporting modifications should be selected to suit your intended tuning stage.
