WTF'S UP WITH THE CAPS? LOL
Im pretty sure your fuel rail is fine with the mods you have though

If you have an upgraded fuel pump, and/or larger injectors, you should bore the rail.

550s are nowhere near large enough for a GT35R. You have 320RWHP worth of fuel with a 600+ WHP turbocharger. You need a full fuel system and a standalone EMS.
