Hey, so i'm getting my hks 264/272 combo cams installed this week and i was just wondering what my gains would be with the current mods (03 VIII btw.)
-Full Perrin Intake
-Buschur tbe
-Nisei LICP
-Tune (Spoolnuptuning) 21-22lbs 93 octane
-Walbro 255
thats about it!

 

290-310 9.5 turbo housing is a killer for power.
