Core charge 6.5 Eprom chip

It is my preference to use the OE eprom blanks as they have proven to be ultra reliable for decades now and cannot be plugged in reversed by accident. Unfortunately the supply of new blanks has been exhausted at GM and my supply is dwindling so we absolutely need the cores exchanged. if you are not able to send yours in advance to be programmed then please select this item and add to cart. -JK
