One of the coolest elements of the turbo Poncho are its dual fuel rail and injector setup. Each bank of cylinders features two fuel rails, and each cylinder has two injectors. Off boost, the motor runs on smaller 65-lb/hr injectors to improve idle quality and driveability. Once the turbos spool up, the 90-lb/hr injectors kick in to provide the necessary fuel volume. All tuning is performed through a FAST XFI system.
