As far as having the dealer flash the pcm, is this a general thing that they do, or do they flash only certain areas of the programming? Also, being that I have a 2000 LS V8 sport, is there any particular part of the PCM that I should have flashed, if this is indeed how flashing works? Sorry, I'm new, and it may be a dumb question, but I couldn't find the answer in searching the posts. Thanks for your help to a newbie in advance!!! :feedback :Beer
