I dyno tested some Mopar ignition boxes years ago and they all performed so poorly that I tossed all that stuff and moved on. Above 6000 rpm all the ones I tested had issues.
So did Mopar Performance - Tossed
Back in the days of Direct Connection , there was actually some pretty good Ignition Boxes along with coils
Now try piecing together a decent so called factory oem system using all this Chinese mismatched crap available today
It’s truly amazing how many different ECU / Ignition modules / coils fail above 5,000 RPMs
In reality FBO is about your only COMPLETE system if you want to stay Inductive
