The ZERONINE DESIGN Stage 01 power upgrade for the Mk4/Mk4.5 Focus ST manual and automatic transmissions provides a substantial uplift in both power and torque across the entire rev-range, adds a host of new functionality and improves outright performance, drivability and enjoyment.
As with all ZERONINE DESIGN upgrades, every product has to pass our own stringent durability testing, which includes thousands of both track and road-mile accumulation whilst monitoring key powertrain and drivetrain parameters. When it comes to performance calibrations, we have decades of experience at both OE and the highest level of motorsport under our belts, so you can be assured that regardless of how you drive your car, or what octane fuel you want to use, a ZERONINE DESIGN calibration will deliver OE-like drivability with robust, reliable performance, lap-after-lap, mile after mile.
