So, I picked up a used 2014 Forester XT Touring. The car starts up just fine and seems to idle fine. So, pretty much all WRX's have some sort of hesitation when accelerating with the stock ECU map. Just a few days ago it wouldnt even plane out with me alone. The past 6 months I have noticed quite clearly that when accelerating the engine seems to 'stall' when it hits 2000rpm till it hits 2500rpm then takes off again. At first I thought it was the DSG working/being funky at slow speeds, but the service department also told me that when the car is first turned on and running at slow speeds, it will usually kick on the air pump.
