well i just got back from getting my exhaust put on. Its a DC Sports, i got it because i have a dc sports 4-1 header. Well, i luv the thing so far, i can tell a difference plus it doesnt sound abnoxious or like a bubblebee. But my question is, do i need to reset my ecu? i think we reset it when i put the aem short ram intake and header on, or shuld i wait till i put the cold air intake next week on , then reset it?
