this is at WOT.
IAT'* are messed up... nuf said.
BLM'* of 137? Your running really lean. What are your 02'* at WOT?
Judging by how high your BLM'* are and your INTs at 128 I can tell that your PCM has learned that you need more fuel and basically is finished learning how much fuel it needs.
I think you need a bigger pulley.
