it was the tune. and i forgot to plug the vacuum line to the fuel pressure regulator. fuel trims are pretty close to 0, which surprises me because I haven't made any maf adjustments.
I built a stethoscope for the engine and had a friend ride shotgun with the computer in his lap with the ear muffs on to listen to the engine and he said he could hear detonation, only on one pull, the next pull was clean and he didn't hear anything
on a side note, i think i'm spraying too much water. I will have to swap nozzles for the medium or turn the water spray off. car felt like a turd at full throttle.
