300/320hp capable but more likely to be 280/290ish when run on our fuel and the knock sensor winds it back. should do the 300 on our fuel once mapped for it and with exhaust/3port/pump/panel filter added then your shooting for 330-350.

 

Sorry ,it's not a version 9. It's the version 8 jdm .i believe from what I have read they are 280 bhp standard..I don't have a graff but was told by the dealer I bought it off that it's running 287 bhp .thanks
