Here's what I got (blue/red) vs bm3 stg2+ ots (green/yellow). 100 RON E10(straight out of the pump), catless DP+TU HPFP.

These are figures at the wheels, computed by RPM ramp-up rate while knowing the car weight, aerodynamic drag/area(guessed more or less), gear ratio, rear end ratio + 4th gear pull on a straight stretch of road. The OTS one looks a bit worse because IATs were awful on that day. I assume they would be neck and neck otherwise.

The takeaway here is no ignition retard and lots of other personal settings I wanted at all costs(exhaust flap closed, much cooler coolant targets, limiters for high IAT/knock etc etc etc). 10/10 would do again.

When I'm done with it I may do a write-up on how to use BM3 at a very basic level, at least to help get rookies off the ground.
