Was just snoopin around jegs and came across this.

What is this, what does it do, and does it increase performance?

 

i think you would get a better response if you identified the ignition box as a msd series 6, i dont know for sure what it does or if its worth it. i know there are a few guys on here using the have used it. the write up says it does it all. lol.
