I figured this would be a good time to start a discussion about fuel rails. I'm trying to figure out the difference between using an aftermarket fuel rail and an oem fuel rail in terms of tuning. In my situation, both rails will use 1000cc FIC injectors and will be returnless. I need to figure out how to adapt a K-Tuned rail to my 06-11 Si without running a return line. IIRC, I need to use the oem fuel damper with my setup. Thanks in advance for your help.
