The factory vacume operated turbocharger control system on these 6.5's is not a good one. Designed to alternately apply then release the vacume signal, the system causes the turbocharger to continually speed up then slow down which results in fluctuating boost output pressure. The system is powered by a failure prone vacume pump which is known to lock up and ruin the serpentine drive belt. These failures seldom happen in the garage.
The Turbo-Master Model GM96 is a simple, bolt on replacement for the troublesome factory setup. It combines with the turbocharger waste gate valve to create a smooth working, fully adjustable turbine inlet pressure (drive pressure) relief valve system. Up to the point of bypass, this system retains precious turbine inlet pressure to drive the turbocharger resulting in a vastly improved turbocharger performance. The engine appreciates the nice steady boost pressure and responds with improved driveablity even without other modifications.
The Turbo-Master is the perfect companion to our Max-E-Tork re-programmed ECM. The two will transform your 6.5.
Not recommended for use with the factory computer programming.
