Experience with JB+ and B58?

Has anybody had any experience with JB+ and their 540i? It seems like they get listed/sold pretty quickly in the classifieds section. However I'm having trouble finding anybody's actual experience owning it.

Reviews seem to be plentiful for owners of the 340i but I know the G30 B58 is slightly different so I'm curious what you all are experiencing. Sadly, forum search and Google search were not very helpful.

Any replies are appreciated, thank you!

the result will be identical to the 340 ... It's a great tune that offers good power for an unbeatable price. It's also very easy to install and remove it need be

If you're out of warranty or don't care about warranty, I recommend a proper tune like BM3 over the piggy back body controllers but if you're still in warranty and that's why you're considering JB+, I recommend getting the JB4 instead. It costs more but the additional logging ability (you need the Bluetooth addon) is absolutely worth the extra dough (and you get more power too). Plus if you decide to go big later on the jb4 can act as a meth + boost controller even if you end up getting a proper flash tune on top.

Just a heads up. IF you have tuned your car and are worried about warranty problems you can have Bmw update your cars software and any trace of tune will be gone.

JB+ was my first mod on my 540i. It was still under warranty and I didn't want to pay the full price for a JB4. Plus, BMS would give me the difference as credit if I wanted to upgrade to the JB4 and send them the JB+.

Its super easy to install and it works. Its really just an electronic boost controller, but its simple and easy to install and remove if you need to. You don't have to worry about trending data or switching maps. It's super simple, but that's the point. Just install and go.
