PS I'll admit something's not right with my parts. Tunes perfect but with all the custom parts I'm not doing what others do power wise.
The oil pump gears wont help produce power at higher RPM. Although, understand that you do not have to produce as much power in a lower gear to accelerate faster than the next gear up. Even if your HP as started to fall, your car will usually accelerate its quickest to rev the engine as high as you can due to torque multiplication of the transmission. Of course once it has fallen to a certain low, that is no longer true... and for each scenario you have to do the math.
