Roger the MSD 8680 will do what you want except that there is no vacuum signal to the controller box. It is a manual knob you mount under the dash. Adjust it to different settings depending on what you are doing. A boost retard box that is used for supercharged cars might work. They have a sensor that adjust the timing and retards. It depends on the boost signal. Best bet is call tech line and see what they say. Most retard and advance timing is either the weights in the distributor or software controlled. Hope this info helps Roger. Rick L. Ps how my job opening coming?Everything is frozen in NJ
