Le kit de cales de soupape de décharge augmente la pression nécessaire pour « ouvrir » la soupape de surpression (PRV). Cela signifie que la pression disponible dans la rampe d'injection reste élevée, comme le demande le calculateur moteur pendant la conduite à plein régime. Réduit le débit de carburant à travers le système de retour de carburant en raison d'un ressort affaibli par le vieillissement.
Il élimine les codes DTC potentiels de faible pression de rampe de carburant P1093 ou P0087 (faible pression de rampe de carburant lors de l'enrichissement de puissance) qui sont causés par une ouverture insuffisante de la pression du ressort de la soupape de surpression, renvoyant le carburant au réservoir de carburant.
