the only way to do it on this model is to play with the wastegate settings and monitor that the car can handle it with increased EGT, and not throw overboost codes. Alex does not have a 552 platform (awd) in Austria to play with and fine tune this, so it's slower, he has to send program vasriations and test them out. We have so far been able to raise boost in the upper RPMs as the ECU does not monitor the boost after a certain point. what would run well on one car would not necessarily work on another, reducing the window for error, and more cars would show problems.
