Default Car Pulls weird while acceleration/boosting

So I noticed even before I put on the mbc that the car feels like it has light bursts of power while I step on the gas. It is not too noticable but I still want to know why it happens. I dont have a boost leak and my spark plugs seem to be fine, they are NGK with .28 gaps but I did not change them yet. The only thing I can think of is something with the fuel injection.

But I have stock ecu and it did it on stock boost, so what could be causing it?

They were already on the car when I bought it but I checked the gapping and its .28

Well it did this even before I put my mbc on and it would hold 9psi after 2nd gear so im sure I dont have any boost leaks. Right now its at 17psi though.
