I have an auto p28 ecu and was thinking about getting it chipped with who? i dont know yet still doin research on that but i want to get feedback as to whats a good rev limit to the b16a since it limits at 8200 and i dont even think its safe or worth taking it all the way down there. I guess there are no power gains at about 7600? so that's why i want to have the right limit to ask for when chipping it. My b16a is all stock just with cold air intake. Anybody know of a good source to get it chipped and changed to a manual ecu with rev limit options etc? Last thing how do i benefit from disabling the knock sensor since i have a cel for that since i still have to hook up the wire? Or should i just hook it up and call it a day?
