Bootmod3 Stage 1 98RON Question

Hi
I just loaded up a stage 1 flash onmy car 2019 m4 competition convertible, it's done 1500 miles (had running in service at 1250 miles).
Using technology in action I'm seeing around:

320kw
Torque 550nm
Oem map
(Up to around 6000 rpm)

After stage 1 (reset adaptations and uploaded the gts software also) I'm seeing 420kw and 600nm
Car is stock
It's not been on a dyno yet.
420kw translates to around 550-560bhp
The torque seems to hit a Limit at 600nm - is this what people are seeing? Does the DCT limit torque I. The first few thousand miles? I notice people quoting much higher torque figures with a stage 1 so I wanted to check.
No fault codes and the car is running beautifully. Also puts the power down easily being heavier!

I'd be interested in your dyno results, as I'm thinking of taking the BM3 route.

Seems high for a stage 1 map?

I'm on BM3 Stage 2 map with a decat ( original non comp model ) and it was dynoed at 535!

I'll get it dyno'd at some point
Not sure how accurate the sport readings are

I've seen similar figures running the same map as you but using the Awron gauge which records maximum figures on a run.

The power and torque figures are derived from an algorithm so I'd just assumed these high figures were a function of that algorithm breaking down as the parameters are outside stock. Whilst the map certainly gives good results, I don't expect we are genuinely getting that power. And equally, I'd not read too much into the torque figures either. I'll check what my torque max is as a matter of interest.

so this shows higher values. I don't they are accurate though
