TBI Fuel Pressure

[Brent Obermiller]

Okay, First as a sanity check: 9-11 Lbs/sq in is bad right?
13-15 would be good?  Second, should the fuel pressure drop
to zero within 10 sec of the engine shutting off? Engine
acts likes it's running out fuel steady throttle up hill,
and higher rpm's (sorry didn't record actual range) WOT. 
Thinking of adjusting reg (for 13-15) and possibly replace
pump. Any suggestions, comments?

Specifics: GM tower and regulator, 92 Roadmaster pump, 2/
75lb injectors, 7747, Summit Racing 30lb fuel pressure gauge
(input side).
