I've seen no indication that was what the manifold revision was even intended to do. I think the best information we got here was that the way they changed the shape of the EGR passages was to make it less likely that the engine gets a snort of condensed water at startup out of those passages, when the weather conditions tend that way. That was kind of an unrelated problem, but one that a lot of new owners of the first Gen 3s were discussing here as soon as their first year of ownership. It wasn't something like EGR clogging or head gasket issues that started appearing on the radar after some time and miles had passed. Classic. They gave you the version of Techstream installed on their laptop. It would be more interesting to know the calibration ID of the ECM firmware they flashed into your car. Techstream will show that on the health check page. There might be other scan tools that can show it too.
