48lbs at idle, almost 60lbs during part throttle, drops to low 30's at WOT and AFR is staying way lean.

Ive got the inline setup from Magnacharger (2003 return style fuel system). Guess my next step would be to drop a 255 intank. Is this setup gonna be OK? (255 intank feeding and inline 255)

BTW, setup is:
6.0 LQ4
Radix 112HH
3.0 pulley (showing 9lbs)
90mm TB conversion
60lb injectors
LT's

I can pick up a Holley 255 locally (I hear it's a relabled Walbro.) Would I be better off ordering the kit from TSP? For a 2003 I believe you have to cut a splice anyway right?

The only local pump I found is a Walbro GSS346. How's this model? It's a 255 according to this link, but the GSS340 is a "high pressure" 255......Don't really know if there's much difference.....anyone?

What is your fuel pressure KOEO? I suspect a faulty FPR.

Where is the FPR supposed to get it's reference from? Vac or Boost?

Both. It should be pugged into the 1/8 nipple on the back of the manifold lid.

rear drivers side nipple by the MAP? That's where it's running from. Is there a problem with having my boost gauge tee'd into that line?
