I have a 2006 WRX Sportwagon with 2500 miles on it. I have noticed that since I bought it when accelerating the car is not very smooth. I have reset the drive electronics twice now. The jerky acceleration is aggravated when the car is cold. Even when warm it is particularly noticable when accelerating hard from 2000 RPM to ~3000RPM. You can still feel it after 3K but it is less pronounced.
Any thoughts? Is this just the nature of the car? Never owned a turbo before.
