Tuning the GT-R isnt going to be as hard as everyone thinks... pretty soon its going to be boost...timing...++ I'm pretty sure the GT-R could make 550hp on a tune alone...
Bigger turbos...more fuel...some $... I wouldnt be surprised if we have 600+ stock block GT-R's flying around soon..

Nissan has pushed the little 3.8 pretty far. I really doubt any big gains will be made with a tune by itself. Let's not forget that there's a slight possibility that it makes that much power already. (My guess as of now is something around 510 . . . with 15% drivetrain loss that would be about 434 to the wheels)
