Question safc issue

Ok folks im gonna try to explain this to the best of my ablity.

I just installed the return fuel line, type s ints, fpr and safc. Now here is the problem i am running into. When at WOT or HI throttle when ever i hit 4600 4500rpm the engine cuts out and the car suputters like it wants to die out. The a/f gauge shows RED for lean, normaly it shows BLUE for rich. The settings on the safc show for that rpm range are 30% (rich) and up. To try to fix this problem i reset the safc and reset all the settings back. For the first few pulls it was ok, then i retested it out later and the problem came back. Its like the fuel custs off at between 4 and 5 rpm. Do you guys know what the problem could possibly be?

Take it to a mechanic dude that sounds dangerous. You could hurt your engine running lean.

Put a real wideband on there and be sure of what it's doing. If you can wait until tomorrow night, I can help you with my wideband (working until then), otherwise don't go into boost until you use a wideband. I don't want to have to help you swap motors out...

Did you ever figure out what the problem was?

For everyones info this has been dyno tuned. This problem started after i left the dyno, so STOP telling me that I need to put it on a dyno because it does not take a rocket scientest to see that my car has fuel problems.

I also called apexi, those techs are not too bright.
