How much boost does the Cobalt/T run stock on

 

15-18 depending on weather and altitude and all that. usually 15 psi.

 

It varies because of the way our ECU is programed it tries to make a certain amount of horsepower as opposed to the same boost level every time. So I've hear it varying from 13PSI on a cold day to 19PSI on a hot day. Sound about right to everyone?

 

Thanks for your help
