I installed both the JB4 and the BMS Intake.

The increased power is very noticeable... kind of unexpected...
The sound of the turbos spooling is much louder
Routing the OBD cable was kind of a PITA

It’s impossible to find any good information on the G05 application. The installation instructions are a little difficult to follow as the photos correspond to an entire different vehicle.

Still no exhaust flap control through the JB4 app, which is unfortunate..

I am thinking of buying the JB4 for my x5 and I'm just wondering if there are any drawbacks to the unit, how does the car shift gears etc. Do you recommen?

My experience with the Dinantronics Sport on the 40i. Would expect a similar experience with the JB4.

I just installed the JB+ to my B58 X5 4.0.
It is easy install, cheap and I feel the gain. I don't care much about the 0-100 time but I feel it while driving.
I'm happy and fun!

**Stay home install!**

Anyone here taking advantage of the EWG connectors yet? They come N63R systems sold within the last few months and really boost performance potential!

Definitely more power and torque. Not crazy but you can clearly feel it.

jb4 installed on 40i

noticeable difference- low end power is much better, but nothing crazy. the acceleration on this truck is quite numb tbh. coming from an f90 so my foot is still adapting to the new normal.

i've gone up to e30 on map 3, pulling strong. planning on testing some absolute maps this week with e30/e40.

I had it on my 19 X5 40i for about 6 months before I traded it in for a 20 X5 M50i. I absolutely loved it, it's a giant difference compared to stock.

I've just had the JB4 and a AA catted 400 cell downpipe fitted yesterday.

Running map 2 on 98, coming onto boost is a lot more noticeable and it pulls to redline harder.

It's not a kick in the back so to speak but I feel like it has livened up the engine. The auto shop that installed it recommended I dont use map 3 unless I add in octane booster.

You can see cables on the passenger side (Left) as the unit is tucked under the grill below the windscreen.

JB4 to BM3

Hi everyone, This is my first post... New to here but not new to modding cars. I have had the JB4 for 3 months. I would say it is noticeable but not life changing. So...

As I type this I'm getting the Pure800 installed, DEM Unlocked, and JB4 to BM3 with a custom dyno tune. So I will have a JB4 for sale hopefully next week.

DM me if you want to sell the JB4.
