Me too I use Ford 30 lbs in my 1990 vert 396 small block.. (50psi on fuel pressure at 100 kpa = 0 vacuum = WOT ).
my 90 it's a Speed Density computer . (I run a single plane)
I admit I'm near to 80% duty cycle at WOT , but I think I have room for some additional fuel pressure .
-Beppe-
P.S. I run "Open Loop" on chip and all fuel tables on chip are fully modified to run i this way. at WOT I'm about 12.5 AFR up to 6600 rpm.
I have all the chips for winter and summer and all is under control even if I run with disabled (in chip) the Knock routines.
my car run smooth on parthtrottle street operations and in FULL race version.
