The ST MK2 is a genuine success story for Ford and even now it is as popular as ever especially within the tuning community with the glorious 5 pot sound. Yes the iconic 2.5 litre turbocharged engine offers potential far beyond the base level, and what a robust platform it is for those extra horses. It might very well be the most modified Ford ever…
Moving to the bigger end of ST tuning and the Sabre Stage 4 options look to double the power and beyond. It does require some key upgrades, but the result is a very powerful car that retains refinement and drivability. Options start at 420bhp+ and for this level we would recommend the Sabre 500RS turbo. This gives exceptional response, but the top end power is very different with a relentless pull to 7300rpm. You can spec your upgrades accordingly for power between 420-500bhp. Options with a standard or built engine, cams, water/meth etc.
For those that aiming to see 500-650bhp then we have full tuning options for all aftermarket turbos i.e. Garrett, EFR, Pulsar including external wastegate set-ups.

Recommended Hardware
The Sabre Stage 4 builds on all the typical Stage 2/3 upgrades. Injectors should be 650-1000cc in conjunction with a high flow fuel pump. You will require an RS MAF sensor and crossover with options to go with the biggest 3″ or 3.5″ crossover pipes. We recommend the Sabre 500RS turbo (requires an RS turbo + fitting kit), but tuning is available for other turbos set-ups e.g. GTX30, G30-660, EFR7163 etc. A forged/built engine is recommended for the higher power levels above 450bhp.
Sabre ECU software upgrades have been developed under many conditions and cars. This process allows us to assess the tuning long term according to specification and variations, not just from a single vehicle.
Optimal performance and drivability will be achieved where typical hardware, conditions and fuel octane are used. Underlying and existing faults should be rectified before installing performance software. Please refer to the Terms & Conditions for more information.

Billy Norris –
From start to finish, Leighton was outstanding. His knowledge, professionalism, and attention to detail were evident at every stage, and he took the time to clearly explain exactly what was needed to progress safely and effectively. What really sets him apart is that his number one priority is always the health and safety of your car and its hardware—nothing is overlooked, and no corners are ever cut.
Thanks to his expertise, I’m now running a seriously strong and healthy Focus ST Mk2 with the Sabre 500RS tune, fully supported by the right modifications. The transformation is incredible—the car is an absolute animal.
I genuinely couldn’t recommend Sabre Tuning highly enough. If you want performance done properly, this is the place to go.
