Vehicle performance tuning changes a car’s upgrades or handling. It does not establish lower server latency, higher client FPS or fewer crashes. The earlier article confused these tasks and its performance promises should not be used as a reason to install a resource.
A source to inspect
The public 30Pio repository for if-performancetuningv1 contains an MIT licence and the if-performancetuning resource. Its configuration defines a tuning-shop location and vehicle-part prices. The defaults select ESX and disable QBCore. This source is provided directly; the contents of the former ad-gated download have not been verified as the same package.
if-performancetuning source and licence
Check integration before installation
Inspect config.lua and the client/server framework calls against your installed core. Review the shop location, prices and notification integration. If you use this repository, keep the inner folder named if-performancetuning and match that name in server.cfg. Do not copy the old start performance-tuning instruction.
Test an upgrade purchase, insufficient funds, cancellation and reconnecting. Verify the actual vehicle change, the money deducted and whether your garage preserves the upgrade. Keep a vehicle and database backup before replacing an existing mechanic system.
If your server is lagging
Measure the slow action with the FiveM profiler and separate script time, database waits and client rendering. A vehicle-upgrade shop is not a substitute for diagnosing a server hitch.
