Hello all, new WRX owner here. I have a 2012 four door with 17k miles. To he best of my knowledge, the only mod is a Cobb intake. I have noticed in 2nd and 3rd gear when I am heavy on the gas pedal, the car will momentarily lose a bit of power at 4.2krpm and then it comes right back at about 4.8krpm and above.
I have never owned a turbo before, but I suspect the problem is in the turbo system somewhere. Or it may be completely normal for all I know. I would love some input from some of you experienced users before I take it in for service. Thanks!
