programmer issues

[wade carley]

I recently got rid of a 2000 superduty and picked up a 99 superduty. I have a superchip programmer and am trying to use it in the 99, my problem is that the 99 has a removable chip in the computer and will not let the superchip download. I have been told to remove the hypertech chip and the superchip will then work. my question is do i need to put anything(stock chip) in the area where the hypertech is being removed from or is just removing it good enough? another question that i have is can i put the hypertech chip back in once i have programmed it with the superchip? Is that a good or bad idea ? will it hurt or help ? I am looking for gas mileage more than more power than I really need. I cannot go back to mini trucks. I am pretty new to the diesel world and do not know alot about them.

Short answer is yes its okay to remove chip the stock is still there and yes you need to do that to use a programmer and no you cant stack them one or the other
