A1000-6 Injected Bypass Regulator, P/N 13109
I have this regulator on my car with -8 in -6 return.
What does the 1:1 ratio refer to when sensing boost?
Does the pressure rise 1# for every psi of boost?

Yes. I have the same one.

So if I get 14psi boost my pressure will rise that much.
Can I figure out my inj flow with that higher pressure.?

Yep, say you have a base pressure of 60psi, Every psi boosted = +1 psi fp.
Example; Say 10psi of boost= 60 base fuel pressure + 10 = 70 total. Dave nailed it on the head :)

Trying to figure out if my 42# inj are going to be enough. I don't think so.
I should be making a bit over 600hp at the crank..

that would be a minimum, Look from 42-55 depending on management.

Yeah I was looking on the RC web site and that's what I come up with. I am right on the edge with the 42's. I may just have to limit the rpms until I can get some 60's in there...
I have a SCT chip and 76mm pro m....

yeah run a msd ignition system and set the rev limiter within a comfortable range, you got the idea!

yeah I have a 6al in the car, plus I think that with the chip a limiter can be set too.
