2013-2019 Focus ST EcoBoost Tuners & Dashboard Monitors

The Focus ST is certainly quick from the factory, but just like all factory turbocharged vehicles, a lot gets left on the table in regards to its PCM/ECU programming. An aftermarket tune can unlock the true potential of your hot-hatch Focus ST without the need for any hard parts. A performance PCM tune is basically new computer files that change a few key aspects of your Focus ST's computer settings like fuel curves, spark timing, and peak boost pressure to get a ton of extra horsepower and torque down to your wheels. Once you've picked out a tuner, go take a look at our Focus ST cold air intake kits or Focus ST cat-back exhaust kits.
