Yeah this makes sense, a log would tell us what the boost target is and what the actual boost you are hitting is. This could be due to a multitude of issues like a failed turbo, loose pipes, broken charge pipe, other leaks etc.
The fuel pump information is also logged (both low pressure and high pressure) so that would also help us direct you into what is causing the issue. Keep in mind that high pressure fuel pump is a common failure and can cause major issues if the pressure isn't building the way its expecting to.
