But probably not significantly more than the outgoing one. And that is the choke point on the engine when it comes to 'easy' mods.
Here is what me and Exage are getting at:
So if the 210 hp/180 whp motor guys were getting 240 whp (+60 whp, nice gain) after mods, I don't think the new ~270 hp (probably ~230 whp) motor guys will see much more than 250 whp after similar mods (~+20 whp). Unless the turbo is significantly upgraded over the outgoing one.

Perhaps I was looking into that Hyundai GEMA engine and it seems like get stuck with fuel delivery on the stock injectors. Over 20psi boost it seemed like they recommended a 550cc or Evo X drop-in (, then a new turbocharger).
I don't really care enough(/lack of info) to find if the injectors have been swapped on the twin scroll (550cc?). If they haven't for some reason, then they know the safe wall at just over 20psi of boost.
