I'm running a cheap eBay billet( procomp I think) and MSD 6AL box( no module needed) and a remote coil mounted to the firewall. It all seems to work pretty well. I like not having to worry about a module crapping out. I had an in cap coil and after one particularly hot road trip it fried. Try diagnosing a bad coil when your on the side of the road. Not fun. Live and learn.
