Just the chip or PROM, but do it with someone who knows has to cut the box and
install it. I like Super Chips 407-260-0838. There may be others just as good.
Also, my tips are for info and I have been corrected several time. So do not

am telling you is what I did and it worked. No more pings. I did not change
the fuel pump, but with the SC I have two pumps already/
