from what i know its pretty good. u just gotta assemble it yourself lol. which i wouldnt trust myself to do. the great thing is that its pretty cheap compared to other ems systems cause you do it all yourself. theres some forums that help with tuning it so i dont think its that hard. but its always a plus if you know someone with the same car that has it so they can help u out.What are your thoughts on MS? I have a buddy who has used or is using MS on his '83 Z car. He has had great success with the tuning. He claims for it to be very user freindly and works great. Especially the V3.
Any comlaints or cons about MS I should know?
