That isnt true - there is a JB3 for the F10 and I've been running it for 6 months. Recently upgraded to the JB4 as I have a MANual (emphasis on the MAN part - I'm a big fan of stick shifts) transmission and the JB4 for MANual F10s was just released.

I found that the JB3 actually feels faster as it has more of that peaky, boosted feel - the JB4 is so smooth and linear that it masks its work.
