That was quick!
I was unaware I was requesting 2.5 bar. Correct me if I am wrong but I thought it was 1.5 + atmospheric pressure. 2.5 bar + atmospheric pressure would be well beyond the turbo's boost capabilities and off the scale in the compressor map.
No, you are indeed requesting 1.5 bar (2.5 bar absolute - its right there in your log).
However, that is still not a good thing, even if it is well within your turbo's ability.
Please reread the tuning wiki.
Is the cracking point supposed to be 0.5bar?
It's supposed to be whatever you need it to be to balance
1) the max boost you can make with the wastegates closed
2) part throttle drivability
