replied to the thread Take a look at my data logs? Car falling on its face
" Only thing I can think of is o2 sensors or o2 sensor connection to the block. If your injectors or plugs were bad, you'd be misfiring or idling rough. It wouldn't be vacuum/boost leak because that would result in a rough idle and poor boost response but that doesn't seem to be your case. I'm just trying to systematically eliminate variables here, but it's difficult to diagnose this kind of thing without the car physically present. Your issue sounds like something that will be a real PITA to resolve, but best of luck. "
