Surely you guys got new injectors to handle the higher flow - I don't wanna go that route, at least not yet. So the 33gph is a match to OEM? I remember Doug posted something on v8sho about an equation that engineers used for the fuel system for this motor. So if this pump I got can put out the same flow and pressure as OEM, then I suppose the equation would balance. I'll dig a bit more into the specs, and maybe give our buddies at RockAuto a call.
