Also, I don't think the engine would have fired if I had connected it losely so all is good. I also maxed out the psi level all the way clockwise to the right (5 o-clock).
So then I took her for a spin up and down the hills, about 10-12 Miles round trip, and quite frankly, didn't notice much of a difference. I had gauged with the sport displays before the JB+ and it had tapped out at 240/300 and I had similar results after the JB+, maybe around 250/310. I drive efficiently most of the time so flooring the gas l is not what I do usually but I did most often in my "test drive" post JB+ installation, but it didn't go past 245-250ish.
Is there a break in and learning period for the JB+? Am I going to feel the difference on the freeway when I pass other cars? Tell me more ...

Getting the same with my 530e JB+. I thought it was working because technically the motor is supposed to be 180hp, but mine is also exactly 240/300. So if that's what you got when stock then that is strange.
