Really learning a great deal from the discussion. I decided to go with AA since I'm getting the headers from them -and- their new exhaust!!! Yes, I'm now the test mule for their exhaust. Also means by default, I'm getting their tune. I don't want any CELs and I want to drive the car on the street some of the time.

I asked them about the throttle hang discussion, here is what he said..."guys are using an N54 manifold and giving up a lot of low end to get top end...that causes some issues". I'm not knowledgeable enough to debate the subject, so not sure if he was accurate in his description of WHY the throttle hang is occurring.

Anyhow, the car is pretty much stripped on the rack, parts going on now. Exhaust and headers will be here next week. AA states it will be a little more aggressive than the BPE, we'll see. He stated another 7-10hp from the exhaust. Will report back.
