All that I have read on this mod has said nothing on resetting the ECU. Is that becuase it has a MAF instead of MAP? If I overlooked the portion where it said to do this I appologize for the post. I know with MAP sensors you need to reset the ECU. MAF sensors are always correcting right? I just did the air box mod on my car but I have not ran it yet. Someone please respond to this post soon.
