  Now with the new ign system, things are

 Is this a reasonable conclusion given the

Is this a stock cam??..

If a non-stock cam, then seems like the plug firing at overlap might be
and emission aid.

Amazing results,  were the plugs changed?.   Was this just coils, and
wires (plus electronics)?.

Wonder if the gm is limiting the coil output somehow on the the oem
coil or if there was a RFI problem with a good coil

  And if it is a reasonable conclusion does anyone know the address and
format of

knew where the
