[QUOTE="Voltwings, post: 14231514, member: 155561"] If i'm looking at this right, your MAF frequency is incredibly turbulent, and your AFR's are kind of all over the place during this pull. Typically as you accelerate your MAF readings should steadily increase as your motor ingests more air. Your Voltages tend to bounce in this pull, and your AFR's bounce anywhere from mid .7's to high .8's / low .9's ... I Dont know if it has to do with your procharger set up's MAF placement, Which im assuming is a blow-through configuration, but it is an issue. The Odd thing is when it leans out your AFR's are almost more consistent than the rest of the pull... i'd almost check for something silly like actually commanding the right fuel targets in that region. Shit happens you know, gotta go back and check the basics. [/QUOTE]
