Finally i managed to upload my last track day's videos. See below.
As i checked the logs with the BM3 Stage 1 tune my maximum boost pressure is bigger with 0.25 bar than stock. The IAT increased only 1-2 degrees if i calculate with higher outside temp as well compared to the previous occasion. Fortunately i didn't experienced any fuel starvation issues. My fuel level went below 1/4 tank and i didn't get limp mode.
