Looking around a bit it seems to get the same feedback as the earlier versions and the MAFT Pro (which I have a lot of personal experience with). A lot of people feel it temperamental and tough to get running smoothly, would go with a standalone if they had to do it over again, think the learning curve was too steep and ended up paying a shop to tune it all... You see the same complaints for anyone running any number of piggybacks though, in this case they're all just rolled into one unit. If the '3' is easier to tune and has a simpler learning cure then have at it. If not you might want to learn on something which isn't going to cripple your car while you figure it out.
