Here is an example of what the high RPM injector body mods can do at the higher rpm for building power. This is just a mild example of stage 1's. In a mild truck, with an original single CP3. On a serious fueled truck using the stage 3 or stage 4 injectors which have the high rpm body mods, and tuned for the high rpm power and with all the right supporting mods, one can really see how the high RPM injector mods would allow you to have fueling up high in the RPM range.
Pretty cool comparison chart.
