pw that low and that kind of power kinda tells me hes not runnin stock injectors.

thats a nice n low pw too. at 3200rpms the injectors are open for roughly ~44* of crank rotation.

compared if someone were to have a 3000Us pulsewidth at 3200 rpms and have injectors open for roughly ~57*
Most people would run that kind of pw or more to make the same power
