[M240xSI]

Decided to pull the trigger and get a JB Plus to hold me over until I'm ready for a JB4 or Racechip. Install took about 30 seconds, super simple and just connects to one sensor. My car already has a catted AA downpipe and a DINAN intake and axle back so this was the next logical step for me.

Put some miles on it and I can definitely feel a noticeable difference. I left it on the default 3'oclock position which I believe is around 4 PSI increase. I didn't feel much driving around town, but there is much more power in the mid and higher RPM range when you wind the gears out in sport and sport plus. Boost comes on quicker and the car feels just right.....for now. For $240 you can't beat it.

I ordered the JB Plus as well. Hard not to pull the trigger with the 100% trade in for the JB4.

Let me know what you think. It's not the smoothest, but adds a nice kick. I'm wondering how much JB4 map 2 would add from what I currently have

I have a used JB+ on my 2023 M240i X-Drive at 3 0'clock position. Other than running 99 octane petrol the car is completely stock.

JB+ cost £25 delivered from Ebay because one of the clips has a slight crack.

Noticeable increase in acceleration and 'roll on' in manual pulls.

Mustang dyno tests showed 445BHP and 475lb ft torque so no complaints from me.

I traded in my 23 330i with JB+ and confirmed with Burger Tuning that I can use the same one on my 2025 M240i...

with 93 octane I definitely feel like I have 440 or so to the wheels
