As I saw on my car, the boost was higher. Here is an example of the same car measured on the same street ( M40i european 340hp version). In the first measurement it was 15C outside and in the other measurement it was 34,7C. The power/torque values are the same, but as you can see the boost was up to 2,5PSI higher to achieve the same power.
