What psi are you boosting? What are your injector duties? You want to have injector sizes that can support your peak power with a max of 85%. With your mods and the power you're making, you're probably getting duty cycles very close to 100% with your injectors. What are your AFRs?

i believe its not really required to stay under 85%...this may apply to other cars but honestly has ANYONE heard of an FD failing because of injector failure?

its not required to be at 85.. 85 is safe range, 90 is pushing it and they might overheat and stick close or stick open.. i am acually running about 93% in-d which i need to get 1200cc, but i would recomment the fuel system upgrade, better safe than sorry
