looks like 31 all around for sub 150 mph single occupant based on the fuel door sticker
tires were indeed over inflated. By the shop when replaced

The bottom two rows apply to winter or M+S tires, which are typically W-rated and suitable for speeds up to 168 mph.
Generally, any pressure between 31 and 38 PSI is acceptable, depending on your top speed and driving style. For spirited driving, 35 PSI on all four corners is my choice as well for OEM/Michelin PSS/4S type tires.

Thank you for contacting Customer Relations at Continental Tire the Americas.
The cold inflation pressure is set by the vehicle manufacturer and applies to replacement tires of the same size. So, we recommend following the pressure listed on the vehicles tire placard. According to the Tire Guide, this is 36 PSI front and 39 PSI rear.

As an aside: I used to use 29 psi on the Sport Cup 2 tyres on my ‘18 GTR as it helped greatly in providing a little more compliance on surface streets; all without any obvious deleterious issues.
