i'd bet a very large amount of money on it. I've seen the truck in person. know the owner/tuner personally very well and he tuned my truck.

 

Maybe a few years ago it was "impossible" but that's because we didn't have the tuning capabilities we do now yes s475 on stock bolts... it's possible.
I'm a test the limits kind of guy when it blows I'll fix it but until then nope. It also was told to be impossible to spool a s475 on stock fuel but it's not... now we have fuel and air. I love finding the "breaking point" that's why I traded cbrahs a built g56 for a stock auto (and I wanted to play with od in mcc for tuning) 30k on the stock auto since it's been in my truck with zero issues and that was after a 900 mile track home in 4th gear due to lack of communication. Early lockup seems to really help. It may break tonight but it hasn't yet .

 

Why all the massive hysteria to hotrod the hell out of a newer truck? Buy an older model like my '03 and the options to tune it "up" are almost limitless. The cost of a new truck, the violating of any warranty, the trouble with getting it "smog checked" if that applies to your state, etc. are all just too much trouble.
HP and Torque are the same no matter the year model, so spend less on an older truck and more of the hotrod stuff.
Just an old guys perspective.

 

50 psi on stock bolts is very common. If drive pressure is in check, I see no issue with it. I was at 550-600 on stock head bolts before I finally decided to put studs in. 50 psi out of a stock vgt turbo is another story...

 

Exactly my thoughts
