Well performance is not something i'm really seeking at all, fact of the matter is, this car is pretty slow already, not really worth trying to make fast, the real purpos of considering MSD is to possibly improve the fuel mileage, after all, strong spark, and even multiple sparks reduces the leftover Hydrocarbons left after combustion, thus resulting in a a very slight power and fuel mileage increase, however i'm only talking about 2-4% at the very most, but seeing the possiblity of $5 gallon gas in the near future, it kinda has me wondering if I can squeeze the mpg just a bit higher. Plus I just like trying out new shit for fun, thats all.
