    2012 WRX LAGGING

    I recently purchased a 2012 WRX, first one and I love it however I have noticed it seems to be rough tuned and between 4-5 thousand RPM there is a very slight lag, has anybody experienced this??

    acceleration just doesn't seem to be seemless

    Haven't heard that one about the 2012s yet...but it's no surprise that Subaru put a . Potty Mouth .. Potty Mouth .. Potty Mouth .. Potty Mouth .ty tune on a WRX. They are kind of known to lean them out a bit to save some MPGs.

    Stock? Mine was like that, flashed to Cobb Stage 1 fixed the issue. The torque seemed to be dropping right were you are talking about.

    Yeah, the stock tune has a lot of peaks and valleys. The fade after 5 grand is horrible. A stage 1 tune will fix that.

    Yeah that is the crappy tune that comes with the cars. Stage 1 vs Stock is night and day difference.

    Not much in gain maybe a few ponies, it will really smooth it out though feel like a whole different car.

    It really is a night and day difference. My car was so much smoother after flashing. You can either purchase a Cobb Accessport and use those maps or you can buy a tactrix cable and purchase a torqued performance map.

    Check out the link HERE for what the Cobb Stage 1 map does as one example [PDF link!].

    You can see the torque curve is much steeper and smoother. This translates to more low-end grunt and much smoother acceleration. You might notice a bit better fuel economy as well, but your mileage will vary depending on location and driving style.

    Not really, should be good for quite a bit HP before you need to switch.
