The following modifications can be used for speedrunning the PC version:

• Juiced LITE patch (highly recommended as it fixes a lot of issues with the PC port; includes patched SR2_pc.exe if you are playing on Steam version);
• Increased Tornado spawn rate (if you want to use the Tornado attack helicopter in your runs).

Other useful tools:

• Saints Row Powertools (if running the vanilla version without the Juiced LITE patch);
• Saints Row Powertools - Speedup Stopwatch Test (if running the vanilla version without the Juiced LITE patch).
