Ignition boxes - worth it for the effieciencies

All the fake MSD boxes had the same serial number....
Now.....I have this PC 2015 I bought for 40 bucks....and drilled out the pop rivets to see what was in it....

you can tell the difference in the idle of engine between the MP chrome box and the PC2015...NO..

the pc 2015 idles alot smoother
