M550 JB4

MoeMo87 · 05-27-2021, 10:50 PM

Hello,

I had the JB4 on my 2019 M550 for about six months. I was impressed with the power improvement and the simple install.
I ended up going with a flash tune from RK and no longer have the need for the JB4 so it's up for sale

$650.00 which includes the Jb4 and the Wireless Kit.

I think it doesn't work for the 2021 m550.
I'm not 100 percent sure though. I'll have to find out from BMS and get back to you.

So I just received an email back from BMS.
They said that the JB4 from 2019 model is the same for 2021 m550i

If you still have it I’ll take it. I’m new to the forums so just msg me and I’ll figure out the rest.

I sent you a PM. Sorry, for some reason I was not receiving notification on my phone.

Correct, includes both JB4 and the wireless kit. I originally had it up for $650 but lowered it to $550.

If you are still interested let me know. It's still sitting in the box in my garage

I didn't get a chance to do a before and after dyno, so I'm not sure exactly what the numbers are. But you can definitely tell a night and day difference after the jb4 is added.
