Like as if the RS wasn't awesome enough, Ford Performance have confirmed they're working on a new calibration for the 2.3-liter EcoBoost four-cylinder that should add some factory-certified oomph to the hot hatch.

The new Ford Focus RS is no slouch. The current car's 2.3-liter turbocharged four-cylinder sends out 350 horsepower and 350 lb-ft of torque to all four wheels. Ford claims a 0-60 mph time of fewer than five seconds. While these are already impressive numbers for a vehicle of the Focus RS's size and class, there are always those wanting a little more.

While Ford won't reveal any details on the new calibration, such as power, price, or availability, but we can look to the recently revealed upgrade to the Ford Mustang EcoBoost for reference. There, $699 nets you a 50-state legal 25 hp and 70 lb-ft of torque, all backed by a Ford warranty. It's hard to say if the gains in the Focus RS will be as impressive, since the 2.3 EcoBoost already makes more power and torque in the Focus than the Mustang.

This tune could be a version of the warranty-backed Mountune kit that's currently available in the UK. It's confirmed for the US, but there has been a bit of a delay while they work out the tune for Americans. In the UK, a Mountune upgrade adds 25 peak horsepower and about 30 lb-ft of peak torque. Expect to hear more details from Ford Performance in the coming months.
