The mountune m260 power upgrade for the Mk8 Fiesta ST takes performance to a whole new level, delivering up to 260PS and 365Nm from Ford’s 1.5-litre, 3-cylinder EcoBoost engine, while retaining the factory GPF and catalyst.

The additional torque is delivered across a wide spread of the rev range, transforming the driving experience with stronger acceleration, improved responsiveness and greater flexibility. By removing some of the inherent bottlenecks in the OE hardware, the optimised calibration increases peak power to between 250-260PS, while still delivering an engaging top-end.

Performance

Peak output is increased to up to 260PS and 365Nm, with the additional torque available across the rev range for effortless drivability.

For optimum performance and reliability, m260 must be used with 97 RON+ fuel and the recommended supporting hardware.

SMARTflash

m260 uses mTune SMARTflash, allowing you to install and switch between calibrations in minutes using the SMARTflash app, supplied Bluetooth OBD interface and your smartphone.

No laptop. No cables. No handset.

SMARTflash also provides configurable live gauges, comprehensive data logging and a built-in performance meter.

m260 SMARTflash Includes:

1. m260 performance calibration
2. Standard performance calibration
3. Anti-theft calibration

• Up to 260PS / 365Nm
• More aggressive launch control strategy
• Optimised no-lift shift functionality

Recommended Hardware

To achieve and maintain the intended performance and reliability, m260 should be used with:

• Induction kit or carbon induction kit

• Charge pipe upgrade

• Uprated intercooler

Important Information

m260 should only be used with 97 RON+ fuel. If lower-octane fuel is the only option available, we recommend switching to the m235 calibration, which is suitable for use on normal unleaded fuel.
