I was talking to a friend of mine today and we were on the subject of mapping the ecu to a stage 1 on his focus. That is what he did. Being that I have headers, cat back, intake, and lightweight pulley can we too remap our ecu's to a stage 1 or something like that? Thanks for anyone that knows and had it done leave some info on your performance improvement thank you!!!
the answer is no, there is no point, you wont gain anything, some people have used "performance chips" but those dont do anything either, if you want a significant amount of power swap your car to turbo or get a turbo car
