Was the turbo completely stock? It looked like you were hitting a max of ~22lbs boost according to the map sensor but that looks like it was a "tuned" max. What kind of boost numbers did you see?

Given the "hydraulic advantage" of about 7:1 inside a stock AD injector, it equates to about 1750 PSI of fuel injection pressure.
It is a completely stock turbo. The 22 PSI of boost is read from the DLC so it's what the computer is "seeing". That is the mechanical limit of the stock MAP sensor, so it's all we get to look at. A mechanical gauge plumbed into the intake tract would likely show about 10 PSI more than that. Not that 32 PSI is
good, but that's the reasoning for the ONLY 22 PSI showing up in the datalogs.
