@Map63Vette Have you seen the AMP EFI Pro Evo + HC? It's their small packaged ECU with high current spark outputs so you don't have to use the quad spark module for "dumb" coils. It also has increased I/O over the old MS3X boxes. Very tempting to upgrade so I can add even more crap to it. You would have to use the Holley Dominator to be anywhere close to the amount of I/O, which would be well over $5K. It's only $1600 with a harness.
