1.1*AFGS isn't always very accurate. Log your car again on the street and see if the AFGS*1.1 matches your HP then.

 

I just checked your before dyno street log and the max AFGS it had in there was 370, which comes out to 407... a more accurate number. Either way, just because the car pulled 400 AFGS on the dyno does not mean it will do 440 RWHP, the 1.1 guesstimate was intended for street (w/real load) logs.

 

So your thinking if I made ~410rwhp, I'd be fine on stock fuel pressure and 30lb injectors? I don't want to run the injector over 80% actual cycle duty, so what should I keep it under on datamaster?
