Sorry for not replying earlier. My computer died a few days ago, and I'm just now getting back on line.

Have not tested it on a Lightning. Posted a thread on modfords asking for a SoCal test vehicle, but no offers.

Several recent installs on Mustangs, no complaints of "blower noise" or other background noise false triggering the system.

As Mike said, the system is a retard box. It doesn't kill the spark, so there is no unburnt fuel.

Using a tuning tool, retarding timing one degree might cause a loss of 12-20 hp or so. If the Vampire retards one of the cylinders by one degree, the drop should be 1/8 that number.

The system must tap into the coil negative wire. It retards timing by extending the dwell, at the coil negative.
