InfiniteBoost
It's literally infinite boost
Ensure you have BepInEx 5.4.21 installed, if you do not have that installed you can find it here
Navigate to the Bomb Rush Cyberfunk folder, if you have the steam version it is located at this path "Program Files\Steam\steamapps\common\BombRushCyberfunk"
Place the InfiniteBoost.dll into the \BepInEx\plugins folder, if you have BepInEx installed correctly this folder should already exist
Launch the game
Alternatively you can use r2modman and let that handle the entire process for you, it can be found here
