Default Why are my datalogs so inconsistant?

I have been collecting lots of logs lately in order to have a decent tune. I usually collect them around the same time every day, coming and going from school. I've noticed that I do not get consistent numbers, specially with boost. Sometimes I see 14.5 psi but most of the times I see 12 to 13 psi. I wonder if this is the nature of the internal wastegate, which is supposedly set at 15 psi, or is there something going on with the hardware/software.

I am attaching some logs for comparison. However, I just noticed that the time I saw 202Kpa was while using tuner studios, but it can be seen that I do not seem to hold boost up top.

Of note, the signal that the waste gate is seeing is post IC.
