Great thread! I have a question about the stock tune on newer WRXs (04+). Ive seen in other threads and this one stating the stock tune is not the greatest and can cause the engine to run lean, leading to other more serious issues.
As said in this post, the problem really arises when aftermarket parts are added such as intake and exhaust.
I have a stock 09 and have begun to somewhat worry that I need to invest in some sort of engine management simply as a means of preventing serious engine issues. (i.e-cobb AP stage 1)
Clarification on this would be greatly appreciated
