I currently have a 2011 EVO, love it, but now I am pondering the idea of going to either a wrx or an sti.
Now, what makes the difference for horsepower? I know the sti makes 305hp and the wrx is 265. I have looked everywhere and cannot find an answer to why the sti makes 40 more hp??? Now, is it as simple as a factory flash? so changing the a/f maps and boost? is there a different intake? different exhaust? Are the turbos the same??? I understand the the handling and the transmission and brake differences, but I am struggling to justify the money for the power?
So main question....why does the sti make 40 more hp than the wrx??
Sorry for the noob question, but I cant find it anywhere
