Now, you make a good point when what i feel like the belt slip which spiked the boost up (what I would call it) it could very well have been this.
but as i was saying, the tuner said that he could tune it a little higher but the fuel would start cutting out at 600whp or so. right now I'm right around the 570whp.

I've been where you are. If it isn't what KingLT1 said, I'd put my money on lack of fuel despite what your tuner said. It's a RAZOR THIN margin on stock LT1 fueling. Especially on a 2016 on the low side. I was hitting 30 lbs on the low size at 7-8 psi.
