Ford Focus RS Gets AMS Performance Tune to 410 HP
AMS Performance got its start tuning the Mitsubishi Lancer Evolution, a rally-inspired rocket that Mitsubishi has only just finished building after a very respectable run. Through the years, AMS Performance moved away from cheaper automobiles to tune cars like the Audi R8, the Nissan GT-R, and all other manner of exotica. Yet the company never forgot its origins in the tuner scene, and with the introduction of the new Ford Focus RS, AMS Performance wanted to return to its roots.
The 2.3-liter turbocharged 4-cylinder in the Focus RS comes standard with 350 horsepower and 350 lb-ft of torque, enough grunt to launch the Focus RS to 60 mph in just 4.5 seconds. But power hungry buyers want more and AMS Performance is happy to satiate these gasoline swilling denizen's need for speed with its Stage One E-Tune.
Thanks to a new ECU flash and a proprietary High Flow air filter, AMS Performance managed to gain an impressive 60 horsepower and 70 lb-ft of torque, giving the Focus RS a total of 410 horsepower and 420 lb-ft of torque. Most of the bump in power comes from the ECU flash, and AMS Performance's expert Engine Calibrators who manage the new tune themselves after the owner logs the engine's ECU data and sends the file to the performance shop.
In addition to the normal tune and its bump in power, AMS Performance also offers a race gas tune, selectable from a COBB Accessport, that develops 96 horsepower and 116 lb-ft of torque, giving the Focus RS 446 horsepower and 466 lb-ft of torque, which in our minds puts it nearly to the amount of horsepower Ken Block is making in his Focus RS RX Gymkhana car.
AMS Performance's E-Tune will set Focus RS owners back a very reasonable $499.95, with the addition of the selectable Race Gas Tune costing $649.95, both of which are reasonable prices for such power gains. And this is only the first of many products to come, as AMS Performance stated that this is only the company's "initial step." We're eager to see what else AMS Performance can come up with.
