2012 A5 3.0TDI S-Tronic remap

[Shiv_P]

Hi all

My brother has an A5 3.0TDI (2012) S Line Black Edition with the 7 speed S-Tronic, and his AUC warranty has run out so he is after a remap. We have heard the S tronic boxes do not like more than 600Nm of torque - is this true? If so is the only option for a remap a custom map with a torque limit at ~600Nm and thus accordingly as much power as the map company can get?

Thanks
