I am confused but if the computer that comes with the cam has the tune for a cam then why do I need to get my car tuned after its installed?

The computer/chip/memcal that comes with our cam and tune packages has the necessary calibration/tune in it. To put it in perspective, all you need to do is install the cam and install the computer/memcal (that we supply) and it will work. No other tune is required.
