I have a 98 LS auto w/ AEM intake and Megan racin 4-2-1 racing header and obx cat back. I am thinking of adding a fuel rail with bigger injectors and adjustable fuel pressure regulator and a vafc controller. I have a set of 380 injectors and the pressure regulator already. I am also adding AEM true time cam gears when i have all the parts together. I plan to add stage 2 cams and springs and retainers later. I have been told this will be overkill on the fuel and will make it run rough. Wont the vafc compesnate for the difference in injector size? Should i wait and get the cams and springs as well as the rest tof the parts?
