The results are just what you want them to be, for me it is just going to be something to do. There is no right or wrong. I will go full engine management, since as far as I have been able to determine, the spark control is where the majority of the gains come from, it will be more of a challenge, and it will keep me busy for a while. At this point another $1500 for the system won't make a whole lot of difference. I first have to buy a tig welder to fab up a manifold, but then I will have a tig welder. This is just a journey, not necessarily a destination.
