Chrome ignition module vs rev-n-nator

Put a rev-n-nator on my car and my chrome box in my tool/spares kit in the trunk. View attachment 1714998280
It idles smoother, starts quicker and runs just a little leaner than the chrome box did. Switched to a Blaster High vibration coil too.
The rev limiter in the rev-n-nator is a nice option too.

Did you have to adjust the timing as a result of it running leaner
