i datalogged it and the 02 voltage stayed where it should be, didnt spike lean when it did it.

Im kinda leaning towards a coil too

I checked all the connections and they seemed fine.

I guess Im gonna try and get some coil packs and see if that fixes it

I tried new coil packs and it didnt work.

Im thinking I could have a intake manifold leak or something.

Since you're running charged air you could spray some soapy water around the intake manifold where it meets the head and such and you may get some bubbles, assuming it's leaking outside and not inside...
