It did??? Did you make changes to your Injection map?
Your injector duty cycles are controled by your inj map not the fuel pump.
Your AFRs are controled by the inj map and fuel pressure, and the fuel pressure needs to be controled by the pressure regulator, NOT the pump or any mods related to it. If the pump is changing the pressure you will never be able to tune the fuel map properly.

Gadd,
What kind of connector did you use to connect the wire into your fuse box? I know you said "spade" aka fork connector, but, I can't envision that gripping the lug of the fuse properly. Did you mean quick-disconnect connectors (square lugs), using the female type? If so, which size (Yellow, blue, red)? I'm also concerned about a connector that'll fit with the wire, vs. a connector that'll fit in the fuse block.
Furthermore, I tried some GM terminals that look similar to the stock connector for the fuse, but the wire from the fuel pump is too thick fit in the connector for a crimp. So, i tried soldering it on, and lo and behold, the wire itself it is a bit thick to fit in the fuse block.
A picture is worth a thousand words. If you would be so kind to post a photo of how you terminated the wire, I'd be very grateful.

Sorry, I think I used the wrong name for the connector.

im currently trying to do this mod GADD's way. shoving up the connector through the fuse block might pose some problems, like for example when you are trying to insert the fuse, won't the connector just slide back down the hole? i'm going back down to the garage to look into it more, hopefully i can get it to work!

This is a great thread, I definitely plan to do this to my apex'i BNR33 pump.
Only problem is, according to Max Cooper's site, the pump is limited to 75 psi by an internal bypass valve. Sucks, b/c if you add base fuel px (40) plus theoretically px drop through system (15), looks like I'm limited to 20 psi with my current setup?
