Just and FYI, I have this combo and I really like it. I have the Juice/A set to 5 with the lowest low fuel boost (number 1) and the EZ on level 2. With the EZ on level 3, I felt like the engine was flooding and it felt slower than level 2. But on level 2 the combo produces really smooth and linear power. I have not dynoed yet but I think I should be in the 500 range. I don't mean to offend any other boxes out there. I just wanted to give my experience and happy customer report!
