Wood,
3 questions regarding your friends 3.2
Where are the cats in his exhaust system? Does he have fabspeed headers with cats incorporated or are they in the mid pipes?
What is the nature of his DME bench tune?
What is the drivability / throttle response of his car like below 4000 rpm?

Thanks. I'll look into the flap valve. I'm stuck on the AFR as mine gets leaner as the RPM's get higher and his gets lower. I kind of trust the readings as I've heard of a few 3.4 swaps having that issue. I plan on investigating that closer. As in another way of sampling and then what's causing it. I don't think a vacuum leak as it seems to rise with rpm. That really seems like a fuel delivery problem to me. I believe I changed the filter already. If I get confirmation from another source that I'm running lean then I might replace the fuel pump or jump up on the injectors. I'll have to see what's my best option
