You got mail, 2000 Silverado HD, 6.0L, 80E.
Hmm, I wonder why someone would put a 99 file on a 2002 pcm. Not really taking advantage of the 2002 pcm.
As far as shifting wierd, I know when someone starts mixing PCM service numbers and OS's that weren't meant to be, strange things will happen.
good luck,
