Do you have any tool for monitoring secondary voltage...?
an oscilloscope waveform of secondary voltage will show if ignition occurs and progresses to completion (waveform will have specific shapes for good and misfire cases);
a xenon tube spark tester shows if there was a current pulse (altho this may not be a good indicator);
( basically, how do we view inside combustion chamber )
thanks for the response joe.. I have not changed any dwell tables. I have the square truck coils with out heat sinks on it i read some where the heat sink coils are weaker. I do have a set of them off a 99 I could use if you think they are stronger.
I have a custom OS and file loaded in the truck. ECU was originally a big block 8.1. Needs this ecu as it has the chip for IAC and not DBW.
Plugs are (3346) BR7EF.. Started at 28 now down to 21

I'm not sure which are stronger... use the coils you think are better, and use the dwell table that goes with them.
You can try increasing dwell say 10-15% and see what happens.

Hmmm, plug gap is getting narrow.
My thoughts also. I dont wanna drop much more.. 18 is the lowest I feel comfortable with.. Im just not sure Im not missing some kind of weird limit table
