Oh yeah, the 100whp over stock will be the absolute "safe" limit that the factory turbo will limit us. Still this gain makes this car a BLAST!

As promised, here are the logs from very early firmware vs the later July one.
July:

Early:
https://datazap.me/u/missiontuning/2...?log=0&data=17

Looking at July version, we have 1045kg/h peak airflow, which translates to 38.4lb/min. This gives you a rough estimate of 384bhp

Now, on the very early update, we get 1220kg/h, or 44.8lb/min. This brings you to roughly 448bhp, or 395whp.

What are the chances of you having the very early production firmware still on the car? Very Very slim. The first firmware (calibration only) "upgrade" was done at the dealers and even possibly Over The Air, since the update was very small in size. The following update included full Program and Bootloader changes that can not be done over the air, so BMW issued a recall.

Lucky for us, our test car was sitting on the lot as one of the first productions, and Over The Air update was disabled. When we went to pick it up, our sales point of contact at the dealer "informed" us about this recall but left the car as is, just like we asked. So the first step for us was to get the car Data-logged BEFORE any updates, then update it to the latest version and log again. If we did not do this, no one would have noticed a difference as nearly every car now is updated past the 086_090_006, either from dealer visits or over the air updates.
