Update:

So after much research, I have decided to order (2) Walbro 485's, a 160amp Alternator, and 4 gauge alternator wire. I will have pics when I install the new stuff. The Walbros in the car right now are hardwired so I will check the wiring to make sure it is a proper gauge from the battery to the relay.

Got my Walbro 485's and the 160a alternator in the mail. Just waiting on the 4 gauge power wire for the alternator. Gonna install the pumps this weekend.

Update:

Got around to messing with the pumps. Had little wiring to do. The car already has 10 gauge wired to the relay. However, these pumps follow too much as of right now. Based fuel pressure is at 4 bar instead of 3, and the fuel regulator can't be adjusted down. So I am gonna have to stage the pumps in order to fix this. So gonna have to run a wire from the AEM to trigger the second pump, and also figure out the relay situation for triggering it as well.

The 485 pump isn't any longer than the 255, it just has a bigger bottom...

Update:

So the pumps have been in for a while, everything seems to be staying sealed. So that's good. Eugene picked the car up this morning to get tuned with Cam, since I can't go myself for the next few weeks. Cam will have to adjust the fuel map for the bigger pumps, and account for the second pump that is set to turn on later in boost. He should also be setting up my anti-lag too. Hoping for some good things, can't wait to hear what's happening.
