Today I re-wired my Walbro 255 and I must say that anyone who is turbo should do this mod. The results were great. My fuel pump isn't even as loud as it used to be, my AFR from 6-7k rpm used to be my lean spot, but now it no longer is. Also, my AFR's do seem to be steadier. And.... last but not least, you can no longer hear when my blinker is on For those of you who don't know what I'm talking about, the turn signals cause the fuel pumps pitch to drop as it lit, then return to it's normal pitch. If anyone is interested, this is where I bought my re-wire kit from. Got here in two days.

One more thing, I do recommend soldering all connections.
