mTune SMARTflash m235 to m260 Upgrade [Puma ST] - electronic download

This option is for you if you're an existing m235 SMARTflash customer that wants to take advantage of the enhanced power and torque output of the m260 calibration.

The mountune m260 power upgrade for the Puma ST takes performance to a whole new level, 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 effortless drivability 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 and makes it equally rewarding to rev!

As with the m235 releases, for optimum performance, engine efficiency and reliability, we recommend the use of the following hardware when migrating to m260:

The m260 SMARTflash upgrade includes two additional performance calibrations 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)




Important please read:
 In order to achieve and maintain performance and reliability, the m260 upgrade should be used in conjunction with the hardware listed 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.

Please ensure you are using SMARTflash V2 accessed via our partner app, ECU Connect.  Once your new calibrations have been uploaded to your online account they are automatically added to your smart device when you next run the ECU Connect / SMARTflash V2 app.

You will already require an m235 SMARTflash upgrade / app to be able to install this companion calibration.

Installing the m260 calibration without the correct hardware may result in failure to achieve the quoted power / torque figures, abnormal running, detrimental fuel consumption or engine warning light illumination or, in extreme circumstances, damage to and / or failure of the engine. in any such instance no warranty is offered or implied by mountune.

By purchasing this product you agree for mountune to send you emails about new updates or technical features relating to SMARTflash. You can opt out at any time.

The phone device is shown for illustration of SMARTflash app only, and is not included with this product.

    M235 to M260 - Superb Upgrade!

    What a difference even from 200 to 235!! I was reluctant and took me ages to make a decision, but Mountune have nailed this! The car no longer runs out of steam high up in the rev range. It's feels much quicker, the throttle response has been massively improved and hardly affected my fuel consumption. The only thing I would say, I have the Puma ST with an LSD and torque steer can occur more now depending on how heavy your foot is. You may need adapt your driving style i.e feed the throttle when wanting to pull away - don't plant it! Absolutely brilliant upgrade and well worth money - thank you to the team @ Mountune

    M235 to M260 Upgrade

    Already running the M235 I thought that remap was good but upgrading to the M260 is all new ball game. A lot more responsive and I would say 10 MPH faster around the local B roads
