I've installed DMDs on my brother's 95GS, my 96SE and my wife's 98SE. I'm getting pretty good at installing them now!
In all 3 cases, the Duratecs were much smoother at higher RPMs. Even if the DMDs won't make the engines bulletproof (and what will?!), at least I can enjoy the smooth operation until something major does break -- then it's 3L time!
