If i change my Camshaft in my Gemini is my Delco gonna sort out the tune for me ,or do i need a new chip burnt. Can i use a Unichip or Intercepter style ECU..

no it will try to adjust the fuel to keep it withen spec at cruise but apart from that it wont change anything.you need to tweak spark advance.interceptors and piggybacks are crap buy a $30 chip burner and just tweak the delco its easier than you think
