(actually rereading it is true at low throttle levels but not approaching WOT)
That isn't true of my 6.2, the amount of fuel injected is limited by the type of injection pump, more rpms at WOT and the pump can't put in anymore fuel as it hits the limit around 1800rpms. Might be why my motor is only 120hp and newer versions are 165hp both NA. Also explains why I initially get a initial puff of smoke which clears as the motor revs at WOT as the fuel volume can't increase due to the injection pump flow rate limit. (REMEMBER I DON"T HAVE A TURBO)
