One of the quickest ways to increase horsepower on your 2016-2018 Focus RS is by using a tuner or programmer. They are extremely simple to use and provide significant horsepower gains in just minutes. A tuner or programmer offers improved throttle response, more power, increased shift firmness (auto), increased rev limiter or top speed limiter or even the ability to switch between tunes. Tuners such as the SCT X4 or Diablosport i2 are capable of storing multiple tunes and feature preprogrammed tunes optimized for modifications such as cold air kits. Unlock more of your 16, 17 and 18 Focus RS's potential power with a tuner.
