Consistent fuel delivery and ignition energy are vital when tuning the 1.6 EcoBoost engine for Stage 2, Stage 3, or hybrid turbo power levels. Prevent lean conditions and fuel starvation under high boost by upgrading to high-flow Fuel Injectors and uprated Fuel Pumps. To eliminate spark blowout and ensure clean combustion across the rev range, upgrade to heavy-duty Coil Packs, providing reliable spark energy for high-output setups.
