Welchys Performance Addon V1.0 is a script mod for Farming Simulator 25 that adds a full tuning menu for engine behavior and visual effects. The menu opens with Ctrl + Shift + N and stores 24 settings separately for every vehicle. The script supports an adjustable rev limiter, burnout modes, smoke and tire marks, plus custom exhaust flames. All effects synchronize in multiplayer and work with configured engine names.
• Adjustable rev limiter: limiter RPM, fuel-cut timing and RPM bounce
• Burnout modes: stationary rev, driving limiter and held front wheels
• Tire effects: white smoke, dark rubber marks, burnout audio and tire chirps
• Exhaust flames: color, brightness, reach and diameter with auto sizing
• Five boost sound profiles: diesel, sport, standard, tractor and supercharger
• Progressive keyboard throttle and exhaust heat delay before flames appear
Every vehicle keeps its own saved configuration, so tuning one tractor never changes another.
