Hmmmm...this is very interesting indeed..your post dave has just made me start to think into more on my problem with running to lean at 8 psi on stock injectors and over 110 psi if fuel pressure..although i dont have any cel's, maybe my FCD isn't clamping at the full 4.5 volts, and making the computer not keep the injectors open long enough for more fuel? hmmm...well any way, its good to hear its figured out man :)
