Sal, I used your numbers again and it started and it didn't die. Although a little rough, it didn't die. What I think is happening is what Lapkritis posted earlier.

Simply, at idle, my pulse widths are too short due to 3 injections a revolution of crank vs 1 per rev making my already big injectors have to fire a third of the pulse width it could be doing causing instability of injections (1.0ms vs 3.0ms).

Once at 1 injection/revolution, it should smooth out. But, retuning has been a bear!

Most hi-imp injectors have dead times of .6 to .9ms and you can not make pulse widths any shorter than the dead time. As a rule of thumb you want your minimum pulse width to be deadTime * 25% so for a dead time of .7ms * 1.25 = .875ms

You can not expect an injector to accurately meter fuel below or near it's dead time. The factory Motronic has a minimum injection pulse time built in and it will NEVER allow a commanded pulse width below this built in threshold. In the 89 stock chip this min inj pulse width is set at .9ms and this is with lo-imp injectors that have dead time of .45ms. Here you see that minInjPulse of .9ms is 2X the injectors dead time. This setup fires injectors 1 time per crank rev or 2 times per stroke.

Bottom line is try to keep minInjTimes at least 25% longer than dead time.
