I don't have any electronic control on my supra yet. I am trying to figure out how far I want to go with this one. For my power goals(400hp maybe 500 max) I am sure that a safc 2 or neo would be fine, but I would really like the spark control and speed density that the maft pro is capable of. But of course this would be quite a bit more of an investment. I have read a lot of biased opinions and tech info but when it comes down to it, you just have to decide for yourself based on your power goals, budget, and ease of install/use. I also looked into the emanage and just decided for myself that the maft pro would be a better candidate for that level of performance. There comes a point when a dd should not have any more power. Especially when never taken to the track. I am very impressed with the maft pro's capabilities, but right now I am leaning towards a safc neo running 550s and lex afm. What are your goals for your car? Track or street?
