Thanks Ralf , it´s not so easy to start with the B7 when the first gear is so long !
I have aprox 3200 Rpm in 50 km/h on 1.st gear and when I give full gas nothing happends for 1 sec

and then , wheelspin

This became much more obvius when I raised the boost ....
But as you say , the M3 don´t go away any more when we are up in speed and thats were the old B7 likes to be
I could also change gears much faster but I don´t want to "rape" my darling
