If you choose to experiment, create a secondary PSN account and keep your main profile clean. Never, ever use a save-edited car in a Daily Race. The penalty system flags impossible lap times automatically.

Gran Turismo 7 relies heavily on a "Live Service" model, requiring a constant online connection to play, even for the single-player campaign. The in-game economy is driven by Credits, used to purchase cars and parts. Due to the grind required to acquire high-value vehicles (such as the 20,000,000 Cr. "Legend Cars"), third-party tools like Save Wizard have been utilized by players to artificially inflate their account balances.

Gran Turismo 7 features robust server-side validation. Unlike offline single-player games, GT7 syncs player data constantly.

Even then, server-side checks often reset illegal edits upon connecting online.
