thanks for the help
have you checked w/ the manufacture ? have you tried to
figure out if theres any difference between the pcm's for
your year and the year that the "chip" is in now ?
have you tried google ?
its hard to help you when you dont provide info about the truck
that the chip is comin' out of ! provide vague details...expect
vague responses.
if you can afford to buy another pcm or have a spare one (that
you know works) give it a shot...but if i were you id be doin'
ome SERIOUS checking for model year differences and id contact
the chip manufacture to see what years the chip was compatible w/.
depending on the chip type its either a by-pass (fooler) or a direct
replacement...either way id disconnect the pcm completely from
any power source (batteries etc) before i went plugging and un-plugging
anything into the pcm.
