On runs where I drop any ethanol HP side fuel pressure goes up to 2000-2100 ( low ) . This run had a little left at 13-18% do it dropped a little . Combo is an LT4 Auto ZO6 corvette 2015 upper lower pulley, NW intake x pipe . no cats .

you need to log better channels
desired rail pressure
desired fuel pressure
for those mods you should be ok on maintaining good pressure
Thanks Buddy already done . I was concerned with 1800 psi on the high side .
1800 PSI is far too low
I ran straight 93 and it picked up about 10% . Im running an aux dsx pump , can I increase pump voltage to eliminate that low momentary dip in high side pressure ?
Your low side needs to be 80psi, especially with the DSX low side. There are some things I would think are missing in the fuel pump (fpcm) part of the tune for the DSX. I suspect you're out of fuel if you're not running meth and trying to run anything higher than E20. I doubt you can run any E content at all.
You're barely logging anything useful though. You need to be logging all of the fuel pressure PIDs, Injector pulsewidth, SOI ,EOI , and Injection Window.
Also, did you remove or replace the check valve in the fuel line? The 2015-2016 Z06's had an issue with the check valve on the low side. This needs to be replaced with a 2017+ version to correct the flow issue.
