I have on 02 Envoy and was able to view the cam phaser desired and actual angle through Torque pro. Mine will max at 20 deg momentarily but regularly will not go past 19 deg.
My buddy has an 05 and I can see 23 deg on his.
Also, I will get 19 deg fairly early, around 2200 RPM and will back off as I apply throttle, maybe to maintain vacuum, not sure.
Is that the norm for the early engines?
