On a budget. Do I go with a Holley Black, low pressure piston lift pump, or a 2nd gen 12 valve lift pump and regulator? I think a FASS or Airdog is out of the budget, or do I just go with another diaphragm pump?

 

I'm running a Walbro inline on my '06 with a regulator, and it keeps up fine at 650 hp. They are ~ $100.

Do not go with another diaphram pump. LP Piston pump works well, i cannot pull mine below 5psi right now with 10psi at idle (40psi boost@wot).

Also, upgrade the fuel line size to/from the tank. That will help aswell. I havent done this yet.
