2019 BMW X3 XDrive30i

Hey guys! Are there any options for a rear diffuser for my x3 30i (non m-sport). This is my current rear end. I hate the stock diffuser and the silver part. I am wrapping it black, but, i was wondering if they make any rear diffusers or if anyone has found one for this car (besides maxton’s design rear diffuser which is just slits, but if there are no other options i’ll just go with that one)

thank you!!

BM3 B46 Stage 1 - Burbles work while driving, but silent during stationary revs (and vice versa)

Hey everyone, I’m having a weird logic issue with my 2019 X3 (B46) running a bootmod3 Stage 1 OTS map. I can’t seem to get the burble settings to sync between driving and stationary revving.

The Issue:

  • WHen On OTS Settings: I hear burbles when revving in Park/Neutral, but it's basically silent on deceleration/overrun while driving.
  • On Custom Settings: If I switch to a "Custom" configuration, it’s the opposite, I get the burbles I want while driving, but the car is completely silent when I rev it in Sport/Sport+ while parked.

When I run the Custom Burble settings, this is my config:

  • Min RPM: 1200
  • Min Speed: 0 mph
  • Aggression (in Sport): 8.4 (Custom)
  • Mode: Testing in Sport and Sport+

I’ve tried matching the Sport and Sport+ sliders exactly, but I can’t get them to work in both scenarios at the same time. It feels like the ECU is switching between different tables for "Neutral" vs. "In-Gear" and the Custom settings are only applying to one of them.

Has anyone found a specific slider combination or a "Max RPM" / "Vanos" setting that fixes this "either/or" logic on the B48/B46 platform?

I am running a catless downpipe.
