11-16 Duramax LML BD Diesel Allison Pressure Controller Differential Electronically closes off turbocharger vanes

Electronically closes off turbocharger vanes to provide engine braking

6l Duramax LB7/LLY/LBZ/LMM/LML in 2500 & 3500 applications

When this happens

increasing flow capacity and reliability over the factory pump

They are center-less ground to assure perfect concentricity

11-16 Duramax LML BD Diesel Allison Pressure Controller Differential Electronically closes off turbocharger vanes25% to 115% more theoretical holding power Delivers up to 275psi line pressure at WOT Only active when boost over 15psi, unlike solenoid foolers or plugs which are active all the time Does not create parasitic load or extra heat when inactive Does not cause clunky or unusual shifts due to dynamic activation No transmission relearn required Installs in under an hour Warranty Parts 12 Months
