I assume you meant to say O2 and not p2. It does look like your O2 voltage is relatively low with your max voltage just barely breaking 800mv. Now im not a tuner expert by any means and im still learning myself but i believe the max values should be mid 900's. Now whether this is from a bad O2 sensor or not i cant say for sure but it does appear that your O2 readings are somewhat all over the place. I also noticed that your timing at wot seems pretty low too.... around 15 degrees. I would think if you pulley up and add timing you would make more power even tho it appears you have all the neccesary supporting mods in your sig. Looks like you dont have much kr at all which is good of course but i think adding timing is going to make kr jump up. However if you do indeed have a bad o2 sensor i would change that first and then bump the timing up and scan for kr and hopefully you wont have to go up to a 3.5". Hopefully someone with more tuning experience will chime in and correct me if im wrong on any of this. Goodluck
