MSD Blaster 2 with electronic ignition

Has anyone had luck running a Blaster 2 coil with a stock Chrysler electronic ignition system? It say's it is supose to work with electronic ignitions, as long as you don't run the balast resistor.Their balast resistor is to be used with points only.
I spent tons of time on the net, and couldn't find any straight answers, even at the MSD web sight.There are several conflicting stories about which combo of balast resistors to use with it.
I put one on my wifes 360 race Dart, and it starting craping on the dyno at about 5,000 RPM's. We switched back to the stock coil with no issues, then switched back, and it started craping again.It did this with any combo of Balast resistors, and also with no Balast resistors.
We took it back and got another new one, which it is still in the packaging, so if they don't work I want to sell it as new.Just wondering if the 1st one was DOA, or they just don't work with electronic ign.
