I have it in a MBX7 I am running carbon shoes 1.0 springs. What I like about it is I have not had to mess with the tune much after the first gallon I set it the way I wanted and have left it alone. The tempetures I have ran in have varied about 20 degrees and all I have had to do is adjust my high speeded needle a hour or two and it was fine. The best way to describe the way it feels is crisp. I just hope it holds up like the Novas if it does I will buy another one.
