I dunno what the BLACK BOX is doing to the fuel... but once out.. everything is fine!
Running now with an 1.7:1 AFPR... working very well with the 1.8 injectors for fuel.. but can't really tell once its on the dyno and cheak the A/F.

As I recall, the black box was pretty heavy-handed...I think it just fooled the ECU into thinking it was running cooler (like a 160° thermostat would) at all times which makes the car richer. It was pretty basic.
If you're only running a 1.7:1 AFPR now, and not the 12:1 Vortec, then you're running too lean at this point

yeah, 1.7psi of fuel for 1psi of boost. = ( 1.7 x 5 ) + 50 = 58.5psi of fuel.
265cc injectors at 58.5psi of fuel can fuel 140rwhp, I'd say that's cutting it close.
are you trying to say 1.7:1, 3.4:2, 5.1:3, etc.?
