Ok so my Cruze falls on its face at high engine load like in 3rd-6th gear and I hooked up to a scan tool to check if there was codes and no codes so I looked at live data and my map sensor is reading 14 hg at idle and 50 hg at full throttle pulls I think those readings are wrong for a stock car replaced o2 sensors still does it maf is like a month old. I converted 50 hg to psi on Google and it says 50 hg is 24 psi of boost so I think that is a little high for stock.

So I'm wondering if my map sensor is reading wrong then because 50 hg equals to 24 psi and that is what the ecm is showing the map is reading at wot 3rd gear pulls with hesitation like it falls 9n its face I thought maybe the wastage was stuck closed not allowing it to open up causing the turbo to over boost
