    Has anyone ran the 8 plus box? Have you exceeded its capacity? Pros, cons, issues? I’m seeing they compare it to a 20 amp mag.

    With a 16v battery they exceed the 20 mag. We run a 8 plus at 16v on a Street Outlaw deal. 14-71HH at 42 psi boost. We push it with .020 gap on the plugs. Do have to stay on top of the distributor cap, It'll start tracking after awhile.

    Ever experience a weak or tired one? Would leaving the ignition on for an extended period of time, like until the battery died, affect the unit?

    Well,...everything has a life cycle. But without any activity other than being energized. Wouldn't think it would be of any consequence. Weak?... Usually they work or not.
