Our fan was staying on all the time and the dealer replaced our ECM about a week ago. I guess we'll have to take it in again to have the relay replaced.
When I took it in, I also complained (again) about the jerky acceleration between 2-3k rpm and was told (again) that it was just the turbo spooling and was normal.
Now with the new computer, our wagon feels like a different car. Even my wife was amazed at how much more smoothly it ran, and she didn't think there was ever a problem.
So thanks, Turlock Subaru, for inadvertently fixing a problem that you refused to aknowledge.

P.S. If you have the computer replaced, be sure to bring all your keys to have them re-programmed.
