Alright, have a few questions. First, where can i get an extra pcm for my car and what do I

need to look for when I buy it (vin codes, part #'s, etc.). Will the pcm be a plug and play

type affair or will I need the vin switched, or anything else like that. Im looking to get the

extra pcm to get a tune on, would it even be worth tuning whats in my sig? What kind of

gains would i see? I want to keep my stage 2 pcm for warranty work and would like to lean

out the afr and bump up timing on the spare. Any help would be appreciated, thanks in

advance.
