I want to upgrade my entire ignition system. Whats the best one? Ive been looking at the MSD 6al. any thoughts on it? I like the built in rev limiter and thats going to be a must, I dont want to worry about over reving my engine if I mis a shift. or is there another one I should check out. Ive heard good things about DUI but i havent really researched them alot. And what Distributor and coil should I go with?
