Not sure where to post it, but this thread seems to be a good place.
I got my AW 1M a few months ago.
- BSR stage 1 tune: +44 PS and +67 Nm advertised with engine warranty
- N55 midpipes
- Wagner intercooler
Tested (Dynapak) last week outside in 25 degree C: 414 PS (368 PS rear wheel) and 636 Nm
The M mode did increase the torque between 3000 and 5000 rpm, and the power between 4250 and 5000 rpm somewhat.
Most torque between 3000 and 4500 rpm while most power between 4500 and 6500 rpm.
The car is used on local tracks more than on public roads, and so far everything is working just fine (oil temp max 120 degree C).
