That blos sounds good, are they any harder than iMpco and gra to setup and tune? I'd like vapour injection but at around $3000 for supply and tune, then.me doing all the fitting, it's just ridiculous when I have a gra setup in the garage that is capable of big hp. Any idea who.has the blos.mixers? Never heard of them before. This setup might be a lot easier than I thought
