This is why i asked about the boost, I had a cm870 after a head install that had crazy egts, narrow powerband and low boost. pressure tested cooler, tested boots vice grips on turbo actuator, timing on cams...ect drove me nuts. turns out the guys who put the head on used the ecm shoulder bolts in the ecm cooling plate and it was tight but wouldnt hold more them 25# of boost. The bolts topped out before sealing the plate to the head. Honest mistake but they walked away from it.... worth a look
