Haltech Elite Fuel Management System

Haltech Elite 550 Fuel Management System

Ditch the headache of wrestling with ancient, 20+ year-old factory fuel injection electronics or uninspired setups and bring your classic rig into the modern era. To create a top-tier engine management solution that is incredibly user-friendly for beginners yet fully versatile for advanced tuners, we partnered directly with the EFI specialists at SNP Speed Innovations (#TunedbyGabe). The resulting Haltech Elite 550 Kit completely revolutionizes how your Toyota 22RE performs, delivering crisp throttle response, modern reliability, and total tuning control.

Designed by racing fuel injection specialists, this kit provides a 100% brand-new, standalone engine wiring harness to completely replace your factory wiring. This makes it the ultimate, stress-free option for anyone performing a carburetor-to-EFI conversion or refreshing a corroded, brittle original harness. Best of all, it arrives with a pre-loaded startup tune directly in the ECU. This allows you to fire up the engine immediately upon installation, though further custom tuning will be required before hitting the street or trail. 

Specialized online technical support and remote online tuning sessions are available solely through Gabe at SNP Speed Innovations.
