i have a walbro, 12:1 fmu and the inline pump from the drag kit... on stock injectors. Think 7psi on a drag kit is too much?

btw, this is in an LS

 

from my experience the walbro and the inline is going to make you run to rich. just run the stock intank with the inline if your using the 12:1 disk. I'm boosting 7psi daily on my b16 and it runs great(knock on wood)

 

i run stock fuel pump, inline pump, and 12:1 with 9 psi was a little too lean (shitty fuel system cant handle high pressure) but 8 psi seems better.....but then again im a cheap bastard and go by the color of the plugs, which is not a good indication compared to a wideband or a real a/f reader

 

my plugs are kinda whitish around hte edges, but also grey/dark in the middle... its a weird color. opinions? they only have 50 miles on them.
