Redline on the .970 3.5l is 4,100 rpm. If I had been holding the kickdown switch it would have shifted a bit later. If you look carefully you'll see the shifts happen just before the gear markings on the speedo. IIRC boost is 13 PSI last time I hooked a gauge up, I want to double check it.
A prior owner had the engine replaced with a Mercedes reman longblock. I have not adjusted anything on the pump yet. Eventually I want to turn it up to W140 / .971 specs.
