I just talked to a buddy who owns one and he tells me only some of the injectors work in 1st gear up untill 6 or 7K?? Why is this and have you changed yours or is there any reason to do so. Thought it might be to keep the front down but that dose not make sense to do so at low RPMS. Clue me in if you know. JS

theres 2 sets of 4 injectors ..4 on the throttle bodies 1 on each body and 4 injectors on top of the air box aiming downwards into the body stacks, into the bodies, from what i understand the 4 on top start working in the higher RPM i think at about 10,000 RPM..after that higher rpm all 8 work together..the 4 lower injectors stay on all through the RPM..
i guess the reason is ,if all 8 injectors are pumppin gas at low RPM the engine would flood with gas,,so at a higher RPM theres more air gettin forced in(ramair and the suction the engine makes)so the extra gas gettin pumped in burns,more air,more gas=more HP
sounds good to me :? :eek: 8)
