Hello everyone long time no threading lol

Anyways I have two questions without doing much research thought I might ask
ya'll

# 1) Is there a universal seat cover set that is out there for my 02 gtp sedan? Thanks much

# 2) What all can be done with having the ocm programmed? What are the benifits and are they worth it
and if I found someone to do it what is a reasonable cost I should have to pay?

Thanks again everyone
