  1. Wrx sti 2011 tune

    General Subaru Discussion
    So I just bought a 2011 wrx sti the person before done stuff to it which makes the car stutter if you punch it and in high rpm and 3rd gear has no power. Does the car need a new tune ? Would you think the tune on it now is causing that issue. Other than that the car runs normal
