Boost Spike

So my engine sounds exactly like the one in the video below.

I hooked up a BT scan tool today and logged boost pressure to see if it looked normal. I was getting spikes up to 14 psi on a completely stock setup. Is this normal or an indication of a problem? I know the BT tools isnt the ideal tool for logging boost so i'm thinking it could be due to that.
