Tech Resources:
Extra return spring required for installation. Throttle should not be forced past fully open, rigid positive throttle stop on pedal is needed to achieve this. For positive manual throttle return, a toe loop on pedal is essential. For boosted applications, a cold pipe pressure relief set at or below 80 PSI is mandatory.
