Holley sniper with MSD6 controller

I am not sure if the Sniper would interface with the MSD6HEMI, it would probably have to be run fuel-only (much like a carburetor). The Terminator uses the HP ecu so in theory you should be able to remove and sell the MSD6HEMI and run everything off the Holley. A call to Holley EFI tech support could clear it up for you.
