The Ford Focus RS ECU Tune is done by VR Tuned via the OBDII port. The cars 2.3L EcoBoost engine is already a load of fun to drive. With a new Stage 1 calibration, you are able to gain improved performance on the engine. The biggest difference when you flash your car is the overall driveability improvement. Your car will have much better throttle response throughout the gears. Where your car is sluggish off the line, huge gains of torque come in giving you a vast improvement of your 0-60mph time. Depending on mods, the midrange can increase through the curve and the top end pulls harder to redline. As tested on our Mustang AWD Dyno using 91 octane and an ambient temperature of around 90F, we noticed some great gains over stock. The Focus RS has a very small turbo and even with proper air flow during testing conditions, it really runs out of air. The drivable improvement where it really matters is evident from 2900rpm to 4500rpm where the peak gain is near 40ft/lbs of torque. The car has some nice horsepower increases as well from 3000rpm to 4500rpm mark before the factory restriction comes into play. At 3300 to 4000 rpm we say a peak gain of nearly 30 horsepower. The top end of the curve has a consistant gain of around 10-12 all wheel horsepower. As displayed on the dyno screenshot, the car is making 298.3 awhp with a correction factor and nearly 360ft/lbs of torque. Since this test was done on 91 octane, a 93 octane or higher vehicle will produce much stronger results. With the addition of free flowing exhaust components, the mid to top end power range will also increase dramatically.
