I have a far amount of time tuning a 1240 BB rt with a areocharger and it has a attidude controller that has been working well (on the dyno) to this point and is fairly easy to setup.
They are setup in stages somewhat like a carb,low,med,high curcits and boost referance as well you can change the speed in which some of those stages come in.
I'm in no way a expert on these controller but I can say they do work.
