Did you get any feedback from the shop what numbers they got out of stock S550s? I know every Dyno is different and your DH is inline what others have dyno'd. I ask because some dynos do read lowers than others.

419 hp and 367 torque is quite low... They advertised some 500hp and if we calculate in an approximated drivetrain loss of 12-14% it's still low...

Most S550 Mach 1s had better numbers.

That’s not far off from what an M240i makes on the dyno.

Dynos are a finicky tool. Good tool for detecting degree of variance but not good (ie perfect) for comparing a to b.

Different Dyno, but my 2020 GT did 419rwhp stock

That's it - different dyno. However, your numbers are feasible and pretty common. Most S550 GTs had somewhat of 420hp.
My car also made 393ft/lbs of torque. With the Ford Power Kit I made almost 440rwhp and 400 ft/lbs of torque with 93 Octane and a high flow air filter. Not the stock one that came with the kit.

I am a little concerned about the numbers of the S650.
