Well the old Chrysler system dates back to the early 70's and it makes no more power than a good dual point on the dyno, so for that price what do you have to lose? Looks like a DUI type system with an external coil. They got some rave reviews in a Mopar magazine. I think Steve Dulchich is a reliable source, and if he says it's one of the best upgrades he ever did and instantly made the engine start and idle better, I believe it.
