Oh ok, I'd hit 400kw with those sort of mods? I'd definetly talk to my tuner if I can un-restrict it, most people are running 400rwkw or under on a stock FG F6 turbo as my tuner has also told me, above 400 it will definetly need to be replaced I was told, it'll just be a street car, run a time and see what I get.
