M275 max boost?

Could some one tell me what the max boost pressure allowed by the stock wastegate on the 5.5 v12 600 engine is?

On a stock vehicle you'll see around ~13-14psi at redline. Even with a tune boost will taper off on a factory turbo car.

Thx. R Martin, I am just posting a picture of my new billet wheels on my build thread.

Wide-body sl600 v12, let me know what you think
