More boost w/ lower IAT's?

I've noticed that in the morning I can get around 9.5psi, and then in the afternoon I'll get around 8psi at the same boost controller setting. The difference between IAT's is 20-25F. Is this common?

I am not sure why your boost numbers would change, however cold air is much more dense meaning more oxygen and more power.

cooler, denser air will create more boost than hot air. seeing 1.5 psi difference is pretty typical. just make sure your tune is ok for the extra boost.
