So I had a 4.3l maf on my 5.7l just to get it running. This past week I swapped to the propper 5.7l maf. As expected, it thru my VE table off and I started to adjust it.

I have adjusted it 10 times.... At idle this thing is sputtering running rich and it still is asking for 6-10% more. Other areas it keeps asking for 20% fuel in areas that is already at 91ve. If I raise it more, its going to put my ve over 100.. which if I'm thinking right, that means my motor is actually "boosting" itself correct? My fuel milage has almost cut itself in half.

No way this motor and setup is able to be self boosting. What else should I be looking at that is wrong?
