Hey Everyone,

I have an '05 WRX with approx. 1800 miles on the motor as of today. I have recently (few days ago) felt a power loss. When the car only had about 1000 miles on it, and when I would step on the gas, at about 3800rpms (i'm guessing) boost would kick in and you would feel the surge of power, and the car would haul. But, now it does not do that, and when I step on the gas it feels almost naturally aspirated, and does not have that surge of power anymore. I have not installed any of my up-pipe or down-pipes yet..... The car is still completely stock.


This is a pain in the ****!! Does anyone have any clue as to what might be happening?
