I'm running 13-14 lbs 6.0/whipple with fast 65lb , single 450. I have plenty of fuel. Your running twice the pump, injector size etc...

 

Well it looks like 408GT may have called it correctly. I took the passenger side injectors out and got some trash out of them. I'll pull the other side tomorrow to see what's in there.

I thought I blew the hoses out good when I made them up but apparently I did not, lots of little black bits of rubber.

 

If you haven't already, I would check the socks on the pumps. When I put mine together, I assumed my new gas tank was clean. Little while later I was having fuel problems. There was scuff pad materiel all over socks. Must've been left in tank at factory.

 

You should put a filter on there while you are at it.

 

Just to post results I can now hold the 11.3 AFR at 60% duty cycle after cleaning out the injectors. Car is really hauling *** now.

Had to lean the entire fuel map out considerably to get it to run right.

I ordered a new fuel filter to install as well. I believe the crap in the injectors was from the build but it needs a filter anyway.
