Max horsepower?
Hey everyone, i've had my 05 STi for over a year now and have no mods at all. does anyone know what the max horsepower i could get of off a stock fuel system would be? Please let me know, thanks!
im runnin 93 now for best performance but i didnt know if i needed to upgrade my injectors or pump or anything cause im going to start modding pretty soon. i have a t3 turbo that i want to install within the next few months
