[QUOTE="Maryland dieselnick, post: 1273401, member: 22661"] Yes down shift, giving it fuel, or letting off changes the thermal dynamic thru air flow, fuel flow via different injection duration and injection event counts. Lots of variables and things change the thermal dynamics which only are holding that valve back from closing due to the stored energy in the spring. (Little resistance)It depends on the exact truck and how much resistance is offered. This is why a few cannot manipulate the event and get out of it at all if the resistance is more substantial.
