    Prom chip for DS4 5068 conversion-Auto

    Price: $80.00

    This is a stock HD calibration chip that is used when updating from a 5068 pump to a mainstream (5288, 5459, 5521 etc) pump. For auto transmission only.

    In the interest of preserving this product line into the future using the preferred OE blanks I need to get a core return from all orders. A $100 core fee will be applied at time of purchase and will be credited back ONLY IF core is returned within 15 days or other arrangements are made.

    Core charge 6.5 Eprom chip

    Price: $200.00

    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
