Frequently Asked Questions

The FiTech 30111 system is designed for General Motors LS-series V8 engines. It provides individual throttle body performance and classic velocity stack styling specifically engineered for LS cylinder head port configurations.

No. The FiTech 30111 features self-tuning ECU technology. After entering basic engine parameters via the included touchscreen controller, the system continuously monitors target air-fuel ratios through the Bosch wideband O2 sensor and automatically updates fuel maps as you drive.

Like most modern port electronic fuel injection systems, the FiTech 30111 requires high-pressure EFI fuel delivery (typically 58 PSI for LS engines) using an EFI-rated fuel pump and appropriate fuel pressure regulator. JP Racing stocks compatible high-pressure fuel supply kits.
