I do not have an OBD reader. I tried a few apps on the iphone (like Dyno and M Power Meter) but the results where not accurate nor consistent.

The biggest problem as you say is the launch of the car. Even on same tarmac (I have auto box), the DSC sometimes intervenes more than other times, so it cuts more power or for longer period.
