Exclamation JB4 Bluetooth and Lag Issues

So I've already reached out to BMS, spoken to Terry and Ando so far, great support, fast response times. There are just a couple issues so I wanted to post them all here to see if anyone can figure this out. I've sent the kit back already, they say it was working fine, but it doesn't seem to be solved on my car. They've sent out a new board so I'll update when thats on.

Bluetooth Connect Kit- When I first installed it, the kit was only reading boost on my phone, even on logs. Yes, everything was connected properly, firmware up to date, restarted phone, app, etc.

Throttle Closures- It doesn't happen often but sometimes at the top of 2nd or Mid to Top 3rd, the power just cuts off. Sort of feels like a misfire. Happens in 4th sometimes but not too often

Boost Lag- With the JB4 on Map 0 or disconnected the car feels great and as it should. Particularly on maps 3 and 4, I notice a great deal of lag. Map 2 feels good but a little bit of lag.

Overall, I can feel the power gains and I love the kit, just a few issues to work out.

For reference I have a 2020 m240i 6MT -Mid Pipe Del- VRSF Catless DP - BMS Intake
