Can you get it moving and running under load in the minute it is running? Just wondering what it does under load or if it can reach higher RPMs... To me it looks/sounds like a cold idle issue that would show up watching ProTune I think... My .02 anyway. If the inlet manifold seals were going, and mine went, you would get a code because the ECU could detect there was too much air in the combustion chamber. And you have no codes.
