From what I understand, Petronix does not add nor subtract from the Performance of Points. It is just a electronic switch that does the same task of Points. The only benefit, I know of, is the points do not burn or wear and the rubbing block does not wear.

BTW: I have used Pertronix, I also installed a Pertronix Coil and MSD Ignition wires as well as a "Winterburn" CD. I have used the MSD 6A with good results, but I like the "Winterburn" CD a bit better. I am at present using Points along with the "Winterburn" CD. Only reason is I have had Pertronix fail and it is difficult/impossible to diagnosis the problem. I understand points. The "Winterburn" CD has a switch with CD, Off, Kettering (points).
