Better than stock of course, but in my opinion there are less restrictive options that will definitely make more power at the same boost level.
I offer as evidence the ETS V2 that was on Igor's EvoX made 440whp at 28psi on the FPBlack in an MR. It had all the same mods as Will's car with the exception of Kelford B cams because the S2X was not available.
The exhaust was a little too loud for Igor driving down the road so we switched JUST the muffler setup to the ETS Quiet setup (which is WAY larger than this muffler) and dropped 20whp. All of that was done on an MR which loses more power than the GSR. I have seen stock MR trans eat 9.5-10% power more than the GSR so that would have put Igor something like 480s? Add an O2 dump and that can climb another 20whp on the stock turbo let alone on a Black which really might pick up.

I think 400ish is just a "safe" area, but still not for sure.
@murlo how long did you run the 460 wtq before the block went? Mine isn't sleeved and was just wondering if 420 wtq would be "safe"
It was my rods that went not the sleeves, it was the stock block. Not long at all we'll say.
