Gran Turismo 7

At the Tuning Shop, you can purchase Turbochargers and Superchargers, which will increase the power of your engine and your vehicle PP. You may purchase a few of these modifications during the campaign to increase your vehicle PP, but likely will not purchase 10. To minimize the costs incurred for this trophy, select some of the lowest PP vehicles you have and purchase the "Low-RPM Turbocharger", "Medium-RPM Turbocharger", and the "High-RPM Turbocharger" under the "Semi-Racing" tab. After a few purchases on a few vehicles, you will reach 10 total purchases and earn this trophy.

Bug Note:​ Some users have reported the counter for this trophy to not function correctly. Some have reported that the issue is fixed by restarting the console and purchasing an additional turbocharger modification, though the solution has not worked for everyone.​​​
