ok, here is the set up. 1000cc inj., 255 lph in-tank with bosch inline pump, aeromotive regulator set at 42 psi idle. went on the dyno and saw 86% duty cycle and made 484 whp only on 21psi. isn't the duty cycle too high for this pwr? should be around 65%. give me your reasons as to why I am seeing such high duty cycle with such large injectors.
