Somebody school me on the benefits of both and the negs. I just untapped it for the first time and I noticed I don't have a surging of power that goes up and down, up and down. It does it ever so slightky but it is annoying. But, from what I gathered from my short trip home was that it did not surge anymore, boost stopped at about 25 instead of 35 and I think that's all. But what does it do? Thanks!

 

The tapped wire allows fueling outside of the parameters built into the ECM...

 

Oops, you mean the FPCM.

 

short and sweet: Your box tells the pump what to do after the computer stops.

 

Mine surged with the goofy little wiring connector that came with my Comp. Since mine is already tapped, I soldered the Comp wire to the pump wire...real good connection & no more surging. If you haven't tapped the pump wire, a Blue Chip cover will accomplish the same thing without messing up the wire.
