The Welchys Performance Addon is a script for Farming Simulator 25 that introduces advanced engine and effect tuning. It lets you adjust the rev limiter, build boost, perform burnouts, and customize exhaust flames from a single menu. The addon supports both stationary revving and driving with early shifts under light acceleration. Additionally, it offers five boost sound profiles, including diesel, sport, tractor, and supercharger.
• Adjustable rev limiter with RPM, fuel-cut timing, and RPM bounce settings.
• Burnout mode with white smoke, dark tire marks, burnout audio, and tire chirps.
• Custom exhaust flames with adjustable color, brightness, reach, and diameter.
• Five boost sound profiles: Diesel/Cummins, Sport/Car, Standard, Tractor, and Roots/twin-screw Supercharger.
• Progressive keyboard throttle and 24 per-vehicle tuning settings saved individually.
The addon also includes multiplayer setting synchronization and automatic flame sizing on supported exhaust tips.
