I've got a similar setup to the OP. I run 25mm Conti 5000TL tires tubeless on ENVE 3.4 Disc wheels. I weigh about 175 and I usually inflate the tires to 72psi front / 80 psi rear. If I'm expecting to ride a lot of chipseal on a given day, I'll reduce both tires to 70psi. 70 to 80 psi seems, to me, to be the breakover point between comfort (lower pressures) and improved rolling resistance (higher pressures). Below 70psi seems too squishy and sluggish to me. Above 80psi seems really harsh riding.
I'm accustomed to running tubeless at lower pressures. I run much lower pressures on my wider gravel bike tires. But road tubeless seems to get really sluggish, really suddenly, when you pass a certain pressure threshold.
