hey i have an 06 rsx type s with jackson racing supercharger. i am running 7 psi right now but am running a cal for 9 psi. me car drives fine other than if i am cruising and step on the gas a little to accelerate my car stutters and rpms drop completely almost. anyways, i have attached both my datalog and my kal. any help would be much appreciated. btw i dont think the tune is the problem i think something else is causing it and i am leaning towards my o2 sensor being the problem

You hit open loop just after the 11 second mark, it immediately hit lean cut. You also have some lean spikes between 2 and 6 seconds, and since the car was in closed loop, that tends to support your idea that the O2 sensor is not functioning correctly. Is there no CEL? Do you get the same problem if you go to WOT?

Stop!

Check you have relocated the MAP sensor so that it sees boost.
