3rd Gen Hemi Brothers quick question on Harness'

The original module was and is no longer available. That part number was 56028976AA. It superseded 21 times since then so there are plenty of other numbers to search for.


FWIW,,DiabloSport CMR can tune that old PCM cal ID. 56028976AH is the newest cal ID I show.

Here's the WOT A/F and Timing if anyone's wondering. 5-6 degrees of timing added under 2500rpm and a leaner A/F over 4500rpm will do some good
