What is the Boost Pack?
The Boost Pack adds a 50% XP boost to GRID™ Autosport's career mode. This dramatically speeds up your rate of progress in career mode.
The Boost Pack is disabled by default, but can be enabled by following the steps below:
From the Main menu, select Options & Extras → Options → Advanced Options.
A prompt will appear asking if you wish to view the advanced options. Press the tick icon. The Options overlay will appear.
Select Extra Content from the menu side-bar on the left. The list of DLC packs will appear.
Enable the Boost Pack. Close the Options overlay, then completely close GRID™ Autosport.
Open GRID™ Autosport. After the loading screens, the Title screen will appear. Select Start.
The Checking Content message will appear. The Boost Pack will be enabled during this process.
You can disable the Boost Pack at any time by disabling it in the Options overlay and restarting the game.
