Implant GRX

Implant GRX is a perk in the Fallout: New Vegas add-on Old World Blues.

Effects
Implant GRX is a non-addictive drug with the same effects as turbo; it slows down your surroundings to give you more time to act. It is accessed from your inventory in the Aid section of your Pip Boy, with the supply replenished every 24 in-game hours. This perk can be taken twice, for enhanced effects: The effects of multiple doses are cumulative.
 * Rank 1: it can be used 5 times a day, and lasts 2 seconds per dose.
 * Rank 2: it can be used 10 times a day, and lasts 3 seconds per dose.

Behind the scenes

 * The name is an obvious reference to the opposing car, the GRX, from the two-part episode of Speed Racer "The Fastest Car on Earth."
 * The image for this perk is the same as the icon for the RobCo processor widget, a quest item in Fallout 3.
 * All implant perks from Old World Blues use this image, and they are the only perks that have no Vault Boy or Vault Girl included in the image.

Bugs

 * If having taken the Turbo before entering a loading screen, it will make the loading screen extremely slow.
