One of the most popular performance upgrades for Ford enthusiasts is a Stage 1 ECU remap for the 2016 Ford Fiesta ST 1.6 EcoBoost. This modification involves recalibrating the engine control unit (ECU) to unlock additional power and torque while retaining full factory hardware, drivability, and reliability. The Evo Performance Stage 1 remap is designed to maximise the potential of Ford’s turbocharged 1.6-litre EcoBoost engine, delivering noticeable gains without requiring any mechanical modifications. On a healthy Fiesta ST, power typically increases from the factory output of approximately 134kW and 240Nm (290Nm on overboost) to around 155kW–170kW and 330Nm–360Nm, depending on fuel quality and vehicle condition. The result is stronger acceleration, improved throttle response, and significantly enhanced mid-range performance while maintaining excellent daily drivability.

One of the most effective performance upgrades for Ford enthusiasts is Stage 2 tuning for the 2016 Ford Fiesta ST 1.6 EcoBoost. This package combines ECU recalibration with key supporting hardware upgrades to significantly improve overall performance. The Evo Performance Stage 2 remap is designed to optimise boost pressure, ignition timing, fueling, and torque delivery when paired with a high-flow or decat downpipe, upgraded intercooler, and performance intake system. On South African 95-octane fuel, power typically increases from the factory 134kW and 240Nm to around 180kW–195kW and 380Nm–420Nm, depending on supporting modifications and vehicle condition. The result is dramatically improved acceleration, stronger torque delivery throughout the rev range, and more consistent performance during spirited driving.

One of the most advanced performance upgrades for Ford enthusiasts is Stage 3 tuning for the 2016 Ford Fiesta ST 1.6 EcoBoost. This level of modification moves beyond traditional bolt-on upgrades, combining a hybrid turbocharger upgrade with enhanced fueling, upgraded cooling, and a fully bespoke ECU calibration. The Evo Performance Stage 3 package is designed to fully unlock the potential of the 1.6 EcoBoost platform while maintaining controlled drivability when correctly calibrated. Supporting modifications typically include a hybrid turbocharger, high-flow or decat downpipe, upgraded intercooler, performance intake system, upgraded fuel system components where required, and supporting drivetrain upgrades. On South African 95-octane fuel, Stage 3 setups typically produce around 220kW–260kW and 420Nm–500Nm depending on turbo specification and supporting hardware. The result is explosive acceleration, exceptional mid-range torque, and a transformed driving experience that elevates the Fiesta ST into serious performance hatchback territory while retaining its lightweight, agile character.
