   Steeda Leading The Way in Focus ST Tuning

Ford has hit a home run when they brought the 2013 Focus ST with the 2.0L EcoBoost to market as it provides enthusiasts looking for increased performance and handling in a compact package the added bonus of great fuel economy. With this platform we saw the outstanding potential to take it to the next level of overall engine performance. After months of dedicated research and development, Steeda Autosports is proud to formally announce our Steeda Certified Custom Tune services for the 2.0L EcoBoost powered Focus ST.

Focus ST Custom Tuning

With the stock calibration from Ford Motor Company, we found there is a substantial amount of torque and throttle limiting pre-programmedinto the stock calibration. . In certain instances, we found that programming the PCM to open the throttle all the way could actually hurt power in the low end and midrange. So while we can make the system give us full throttle sooner, we purposely have delayed it ever so slightly – which results in higher power loads and torque production in the low end and mid-range of the power band.

With our Steeda Certified Tune Programs we provide additional horsepower and torque while providing the utmost in engine safety and reliability. Steeda Certified Custom tunes are available for 87, 91, 92, and 93 octane fuel versions.. The dyno gains shown in our graph is our tune for 92 octane or higher fuel, note that gains will be less with lower octanes tunes. As the graph below shows we achieved horsepower and torque gains throughout the entire powerband.

Breaking down the actual peak numbers, the torque peak numbers are the result of spikes from the initial hit, so we will break down the numbers to properly illustrate the gains achieved.

Looking at the peak torque shown of 318, that is a false peak due to a spike from the initial boost hit. Reading the highlighted point in the run at 3100rpm, a point where measurements have now stabilized and you are getting true readings, you can see we’ve gained over 52 ft/lbs of torque and carry large torque gains through another 1,800rpm, torque stays above stock the entire run all the way through 7,000 rpm.

With no spikes to worry about for horsepower readings here we have clean, easy to understand numbers. Peak-to-peak gains were just shy of 15 horsepower, but point-to-point gains are much higher. At 5,100 we see an 18+ horsepower gain, at the highlighted point at 5,700, we see over 27 horsepower. At other points lower in the powerband we have gains of over 25 horsepower. In fact the average gain between 4,000 and 6,000 is well over 20 horsepower. Gains you will feel and enjoy everytime you mash the gas pedal.

Ready to take your Focus ST to the next level? Steeda Certified Custom Tunes will take you there reliably and safely.
