    Hi, I have asked this question before but I still have not received and answer. My question is will the 556-150 work with my Terminator EFI and Dual sync distributor. Thanks Sean

    Answer
    As a blanket answer, Yes, those components will all work together. The Driver essentially replaces an MSD box with regard to wiring and functionality. That being said, the coil driver shouldn''t be used on a higher horsepower application. Anything over 400HP will tax the capabilities of the coil driver.

    Hi, I just received my Sniper EFI and found this in the box. It is not referenced at all in the instructions. What is it for and do I install it with the kit. I have a 350 Buick engine with a Pertonix III Ignition.

    Answer
    Mike, The 556-150 is the Sniper EFI Ignition coil driver module. It can be used in the place of a CD box in installations that need something to drive a coil. If you search the below document for the term "coil driver" you will find several sections of the instructions with information regarding this component. http://documents.holley.com/199r11031r.pdf Since you already have an existing ignition system, you do not need to utilize this component of the kit.
