If its been mapped for the FMIC, (like it has) the the fuel will be set to around 12.4:1 with more held boost and more allows ignition advance. With the OEM SMIC the air intake temp will be greater so the ecu mapping will pull the timing out a little but the boost and fuel will be set for performance not hardware protection.
At the end of the day its commom sense, short burts of power will be fine, but substained racing is going to heat things up quick, just have a quick log of the AIT with VAGCOM and see what sort of temps your getting vs the timing correction.
