Some of the Mopar ECU will retard the ignition timing a little (1 to 2 degrees per 1000 RPM above 5000 RPM :scope) above 5000 RPM
when I first started paying attention to drag race tuning a lot of the faster racers had a switch to turn off one set of points to retard the ignition timing in high gear
It seems like some of the street and strip MSD boxes would also, maybe not as i never used them
