Can someone tell me the significance of what high injector times means. I know that low fuel pressure can be one cause, but if the fuel pressure is fine, what else can lead to this and ultimately affecting performance or pulling timing.

High injector times means that the DME leave the injectors longer open for some reason, the accuracy of the incoming engine temp., Lambda signals, engine RPM, open and closed loop condition, faulty DME and more are there for responsible. If a chipped DME is used it could also be the program. After all, a tuner has only two possible ways to inject more fuel in to the cylinders with the used OEM injectors, let them open longer (too long?) or increase the fuel pressure.
