I used to do that on my old Chrysler 2.2 turbo Shelby Chargers and my Turbo Rampage. But mainly, they are just for looks for most people.
Yeah, I have noticed that as well. The only factory S/C car that I can think of off the top of my head that came factory with a boost gauge was the '05-'07 Cobalt SS. I think the main reason that Chevy decided to include a factory boost gauge in the Cobalt SS was so that it would have the same appeal that the SRT-4 had to the younger audience they were marketed towards. Ask me how I know..... (I used to have an '07 Cobalt SS)
But yeah, I am mostly adding it for looks/aesthetic purposes.
