09 cobalt making more boost
hey, I just bought a 2009 cobalt ss turbo which has a new engine in it and it’s about half way threw break in, I did a small pull last night and noticed my boost gauge hit over 150 kpa, about 21psi roughly. Now I know they make about 15 stock but the person who I bought it said that it’s completely stock other than a muffler. Is there any way to tell if my car has the gm stage 1 kit or if it has been tuned. Thanks for your time!

If it spiked that may have been just a fluke. If you do a full pull and it holds at 20-21 you know its got either a tune or gms1 was installed. like ex said looking at the map sensors will tell you as well.
here is what the 3 bar sensor looks like
Here is where the upper one is at and what the factory black map sensor looks like
