Just a thought.. perhaps you’re overheating it? Apparently these engines use coolant temp to control egts, so after a long hard boost, maybe it’s self limiting to protect engine. Does the power come back after a cool down period?

Would be interesting to know if 22psi is stock boost pressure too, mine only runs 19-20ish.
