Here's my story.. My mods are below, and I begin to run lean at 5500 rpm. AFR is 11.9 at 5500 RPM but on the rise. Now these runs on the dyno were with stock fuel lines, stock fuel rails, a 255 lph in tank pump and an Anderson Big Pump inline pump, along with 50lb injectors and a 1:1 AFPR. Im not wanting to rev this thing high, Id like to be around 62-6300 RPM, and Id hate to spend 1500 to 2000 grand on a fuel sytem for just a few extra hundred RPM. Im just wondering what will get me there? Or what should get me there. I have Aeromotive rails ready to go on and Im thinking about adding some bigger aluminum fuel lines. Do I need another inline pump or intank pump to reach my goals? Any help on this is appreciated because I dont know fuel systems well.
