The direct injection fuelling system on the EA113 engine is heavily reliant on high-pressure delivery, making ignition and fuel mapping optimization essential for unlocking true potential. We supply RaceChip GTS5 Tuning Boxes to safely intercept and adjust sensor data, delivering immediate increases in horsepower and torque. To ensure the spark energy remains strong under increased cylinder pressure, fitting Uprated Racingline Coilpacks prevents spark blowout and maintains consistent ignition timing throughout the rev range.
