TUNING experts Mountune have developed upgrades for the Ford Puma ST and the Fiesta ST.

Two systems are available for the Puma boosting power up to either 235 or a maximum of 260ps to enhance the 1.5-litre three cylinder EcoBoost engine which normally produces 200ps.

The higher powered upgrade is also available for the Fiesta ST and both cost £675 including VAT.

Mountune says both upgrades have undergone a rigorous testing and development process to deliver packages that put the driver firmly in control whilst retaining the cars' feel and include as standard a host of additional functionality, like enhanced exhaust output noise, more aggressive launch control, optimised no-lift shift and an anti-theft mode too.

David Mountain, founder of Mountune, said: "We are delighted to offer our customers, not one, but two new performance upgrades for both the Puma ST and Mk8 Fiesta ST.

"The Puma ST has been well received since it launched and we have worked hard to improve the already impressive vehicle, taking its performance to the next level. The two kits launched for this car increase both power and performance whilst retaining an OEM+ feel.

"The Fiesta ST is a platform that we already know well from our m225 and m235 power upgrades, but m260 really improves this already impressive vehicle even further. Fiesta ST owners are a dedicated bunch who love getting as much performance as they can out of their cars, and we can't wait to start delivering our latest power upgrade to them."
