MSD system and stock ECU

Sounds like he installed a complete msd system dist,coil,6a box which is a very good thing,and just left the factory box mounted in place might have been too lazy to remove it and the factory wiring not a big deal,you can remove it if you like..and trust me the msd system is peace of mind.compared to the mopar stuff...

I will have to agree on this one about peace of mind. Then again, its who you talk to and which system they like better. Just make sure it is grounded well, and that the car, engine, battery are all grounded well too.
