So i need to find me a 94-95 pcm, That kinda sux :). I know a few ppl at the local chevy dealer and i also have access to a tech 2 anytime i need it, Can i do any mods with a tech 2? I know ive seen my friend do tire changes with it. Is that about all the programing you can do with it? How much does a 94-95 pcm go for? thanks Mike
