if i remember correctly there is an external relay and larger gauge wire to keep the pump voltage from sagging. also there are custom lines ran as well and the inj aren't maxed (thank god).

you're absolutely right and anyone thinking of making 450whp or more should always consider the pump mod and make sure to have an the next larger inj than you think you'll need. pushing inj at very high duty cycles is like playing a sub at full blast on a smaller amp for long periods of time w/ small gauge wire...the amp will get very hot, may fry the amp (cut off if it has thermal protection), or melt the fuse.
