which is better the Casper's 16 or the ME 16 position? I just bought a used chip that was supposibly an ME 16 position for 72# injectors, but got a Casper's 16 instead. Is Casper's 16 the same as the ME 16 - it says casper's electronics ultrachip on it? Have I won out or lost out on this deal. Should I be making a fuss?
