Sometimes my Cruze makes 16 psi and sometimes it makes 2 psi. My turbo has less than 10,000 miles on it. Sometimes when I start it up and drive it it makes good boost. Other times it doesn’t make anything. I haven’t done a boost leak test but like I said it’s not a consistent leak. Sometimes it makes 16 psi and sometimes it makes near nothing. It’s a stock tune. I wanna say it thinks it’s getting too much boost? So it’s opening the wastegate? Sometimes I can hear the wastegate opening and closing repeatedly when I keep the throttle steady. Any help? Tips? I’ve been getting the overboost codes along with underboost codes. Ive been researching like crazy for a while but I can’t find anyone getting underboost codes AND overboost codes. It’s a new OEM turbo I thought I would be done with turbo problems
