Description
Unleash the full potential of your BMW M5 F90 with the Weistec Engineering S63TU ECU Tune. Available in two powerful versions — W.1 and W.2 — this advanced ECU calibration delivers groundbreaking power gains, enhanced torque, and improved responsiveness. The S63TU engine is already a formidable powerhouse, but Weistec’s expert tuning unleashes its full capacity. By optimizing fuel, spark, and boost parameters, the Weistec tune significantly increases wheel horsepower and torque throughout the entire powerband.
The W.1 tune offers up to +105 HP and +122 TQ, while the W.2 tune pushes the envelope even further with +125 HP and +142 TQ. With refined throttle response, removal of the speed limiter, and customization options like the "Burble" sound setting, this tune transforms your M5 F90 into an unstoppable force on the road or track. Race vehicle owners can also benefit from the option to disable cold start catalyst heating, reducing excessive noise on cold starts when catalytic converters are removed.
