BMW M340i with JB+

A friend of mine installed my old JB+ module on his M340i Xdrive. I am amazed that the same module could be used in 3 different states of tube for the B58. We tried it on a F46 440i, an X3 M40i and in the M40i.

The power gains are noticeable and nowhere near as harsh as it was on the X3 M40i. For $200 you can't beat it.
