mopar performance ignition miss

IMO; if the ignition was weak enough to missfire at tip-in, then it wouldn't recover and take a load either.
In the past, I have run the Chrysler electronic ignition system, with no problems. In fact, I have subbed in multiple factory slanty or SBM,ECUs from several different cars, with no problems in normal driving. That's the way I prove the ECUs for resale.
I'm not saying you don't have an ignition problem.
What I am suggesting is that it is highly unlikely, when a much simpler explanation exists; KISS.
