mTune SMARTflash m260 Upgrade [Puma ST]

The mountune m260 power upgrade for the new Puma ST takes performance to whole new levels, quite literally, releasing up to 260PS and 365Nm from the ST's 1.5-litre 3-cylinder EcoBoost engine - and all whilst still retaining the factory GPF and catalyst.

The additional torque output is delivered across a wide spread in the rev-range which translates into drivability by the 'Megabox', effortless overtaking and totally transforms the overall driving experience and fun-factor. By removing some of the inherent bottlenecks in the OE hardware, the optimised calibration boosts peak power to between 250-260PS - making it equally rewarding to rev!

Installation couldn't be simpler, as the m260 calibration is supplied on our mTune SMARTflash app which allows for quick and easy calibration changes in minutes. All you need is our app, the supplied Bluetooth OBD interface and your Smartphone; no laptop, no wires, no handsets, no problem!

m260 SMARTflash also includes plenty of user choice as standard, with three specific performance calibrations, plus two companion calibrations (standard and anti-theft) which are supplied with the following features:

  • m260 performance calibration
Increased power and torque (up to 260PS / 365Nm)
More aggressive launch control strategy
Enhanced audible exhaust output in Sport / Track modes
Optimised no-lift shift functionality
  • m260 performance ASMO calibration
Increased power and torque (up to 260PS / 365Nm)
More aggressive launch control strategy
Anti Social Mountune Overrun Enhanced audible exhaust output in Sport / Track modes (for those who really like their pops and bangs)
  • m235 performance calibration
Increased power and torque (235PS / 350Nm)
More aggressive launch control strategy
Enhanced audible exhaust output in Sport / Track modes
Optimised no-lift shift functionality
  • Standard power calibration
  • Anti-theft

In addition, the SMARTflash app, which is available for Apple and Android users, also allows for easy future calibration updates and includes a handy VIN and calibration ID reader as standard.





Important: In order to achieve and maintain performance and reliability, the m260 upgrade should be used in conjunction with the hardware listed below and should only be used with 97RON+ fuel. If a lower octane rating of fuel is the only grade available we recommend switching to the m235 calibration which can be used on normal unleaded fuel reliably in all scenarios.
