# Editing tuning prices We know that every server has it's own unique economy, so we've made price changes as easy as we could. Tuning prices loosely depend on vehicle's purchase price and each vehicle can be re-categorized in-game with `/tuningcategorize` . With 5 categories, the better vehicle a player has, the more they will pay. The easiest way of adjusting pricing is with `MoneyCostMultiplier` which can be found in `config.lua`, which multiplies all prices by this number. When you want all upgrades to be 10 times more expensive than they are by default, just change one number. You can also tweak individual tuning option prices or vehicle class modifiers in `config_prices.lua`. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
