The JB+ can be run at the 0-100% setting which is 0-4psi. Default is 3.5psi.

No idea what you're asking about JB4 but it includes the ability to do more advanced data logging and diagnostics if you need to.

Stock varies from 12 to 17psi, depending on the motor and ambient conditions. Figure around 8-10hp gained per PSI on a 3L.

Don't confuse jb+ with the jb4 they area two different products that can not be used at the same time (ideally)

If you want more control, more power, use the app get jb4 if you want simple and cheap, less hp and easier install get jb+

My suggesting being a jb4 owner is to get the jb4... imo it's an extra 15 minute install but you get some really great features for the price

You can't lose either way though

Ja das weiß ich.. Wo liegt denn der Unterschied zwischen jb+ und jb4 Map1. Aber das mit den 40 PS auf max stimmt ungefähr oder.

Is only the load pressure increased, or are other parameters adjusted so that it runs clean?

It's a relatively simple setup. The JB+ offsets the factory boost target, and the DME closed loop fueling and timing compensate for those changes, the same way they would for different weather or fuel quality.

Thanks for the answer. I ordered the jb4 + and the days should finally come. If I have installed it, how do I best learn to drive it right after installation on the highway and full throttle or slowly

Drive as you normally do. Nothing special is required or we would have said so in the documentation!

Just received and installed my JB+ for my B48 330i. Install was easy, though unclipping the sensor was little more involved than pressing the tab. Removing the engine cover helps give a little more finger room.

Using default setting (did not check the setting), the first hard pull was somewhat jerky, but the subsequent pulls were fine. Actually the jerkiness made it feel like it's faster than it is, and there may have been some wheel slip... lol

It probably doesn't make much difference in daily drive, but the 3-6k rpm pulls are going to help with some spirited driving.

Anyways, pretty happy with it for the cost. Thanks Burger Motorsports.
