1. An injector system for an engine having a first cylinder bank with a first intake manifold and a first throttle valve associated therewith and a second cylinder bank with a second intake manifold and a second throttle valve associated therewith, the first and second throttle valves having a common throttle control, comprising a first pressure sensor in communication with the first intake manifold downstream of the first throttle valve; a second pressure sensor in communication with the second intake manifold downstream of the second throttle valve; first fuel injectors, each said first fuel injector being directed to a cylinder of the first cylinder bank; second fuel injectors, each said second fuel injector being directed to a cylinder of the second cylinder bank; and injector control means for controlling said first injectors responsive to said first pressure sensor and said second injectors responsive to said second pressure sensor. 2. The injector system of claim 1 further comprising a rotation sensor for the engine, said injector control means further controlling said first and second injectors responsive to said engine rotation sensor.
