This reminds me of the old saying, "if you drag someone through the mud you are going to get dirty too." I have to say that the way the first post initially made it sound it was like someone tuned the WRX....nothing changes and they tune the WRX.....they see all these gains. This way of presenting it and the way they talked about the "other tuner" who did the car previously made it try and sound like all of these gains were based off of their tuning skills alone and not acknowledge the fact that the car had other issues.
Again, this is just my opinion of how the thread looked to me, I am not saying anything about anybody or their tuning skills.
