Hi,
one of our german forum members has been to "QAS", one of our fovourite tuners. They installed a catback exhaust, hi-flow cats and headers, finally they made an ecu-reflash. The gain in power is about 40 hp (at the crankshaft): 367 PS (= 372 hp) and 380 Nm (= 280 lbf ft).
This is our memberīs new video:
Please note: the co-driverīs weight is about 100kg

I suppose the run from 0-200 km/h takes about 19 seconds...
best regards
