Right, and that's the point I'm trying to make. For the vast majority of cars, they will sacrifice that tiny extra bit of performance that could be gained just because they don't want to add any more additional costs.

Mmmm, not necessarily. Case in point, the V10 engine used in the truck did not have a coil pack made for a 10-cyinder engine, they used a coil pack from a four cylinder and a six cylinder. Does it work? Yes. Is it optimized for a V-10 in a truck application? No. Are they going to gain an appreciable amount of performance or economy by optimizing the ignition for the V-10 truck to offset the added cost? No. So there's no real point in doing it. What they did works fine for the vast majority of people, and that's okay, I'm perfectly fine with the economics of the whole thing. All I'm saying is that there's a chance that it could be improved upon. I don't know that for a fact, I'm just going on the fact that I know how other aspects of engine design are a compromise all in the name of cost reduction and/or reliability, so it seemed like a safe bet that the ignition system is a possible place to look for improvement. The multi-spark boxes out there exist for a reason, they were an improvement over what the factory offered at the time. They offered an increase in performance and/or economy over the OEM setup, for an additional cost. Most people don't have the desire or inclination to look for improving their car, they get in it, fill it with gas and go, and they're happy with it.

I'm not saying that it isn't good performance, all I'm saying is that there's a chance to make it better with a little work to the ignition.
And I'm not really looking for an increase in performance as much as I'm looking for ways to enhance fuel economy for my car. If performance happens to increase as a result something done to increase fuel efficiency, well then, so much the better.
I'm not trying to argue with anyone, I'm just trying to examine some possible routes to find additional fuel economy for our vehicles. Since the aftermarket doesn't really pay much attention to our Intrepids, it's up to us to do a little legwork and research and see what does and doesn't work. I'm just trying to help, that's all.
