FWIW, I run factory 36/44 in my '02 Cab with the R030 RoW suspension package, on Houston's roads which are not at all brilliant.
Leading evidence: 'Run factory 36/44 in my '02 cab' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace suspension doesn't drive a' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Even before switching to coilovers I run front at 32 and rear at 38.

But seriously...start with the same pressures post-X74 that you ran pre-X74.

Changing suspension doesn't drive a change in tire pressures.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

For street use, same as factory recommendation. IIRC, they are: 36 psi front, 44 psi rear, measured on "cold" tires. Changing suspension doesn't drive a change in tire pressures.
Setting tire pressures for track use is an entirely different exercise, about which there are plenty of threads and even more opinions. I have not tracked my car so cannot offer any useful advice.
Try the it at factory setting and see if the rear dances around mid corner bumps. Although I have gt3 setup, there was no way I could drive at stock pressures. Currently happy at 34f/37r on v12s for street with my custom alignment settings.
Somehow the concept of installing the X74 kit, then running tire pressures well below factory spec because "it's too harsh" does not compute. If you want a plush ride, buy an old Cadillac land yacht and retrofit an air suspension kit.
But seriously...start with the same pressures post-X74 that you ran pre-X74. Pay careful attention to tire wear, both to ensure the alignment you had done after installing the X74 kit is working, and to watch for any premature/unusual tire wear due to inflation pressures. Adjust up or down from your pre-X74 numbers as you deem appropriate.
FWIW, I run factory 36/44 in my '02 Cab with the R030 RoW suspension package, on Houston's roads which are not at all brilliant. While this set up does not have the same cushy ride as my wife's SUV, I'm happy to trade that for razor-sharp handling which is part of why I chose my Porsche in the first place.
It's not about cushy ride for everyone but rather trying to find the best grip and balance possible for your setup and driving style. The settings Porsche recommends is a trade off for the streets and a typical driver in a stock car. Once you change things, even like different brand of tires, those settings although a good baseline gets thrown out the window.
