Update: I used the dashcommand app with a cheapy tablet and set the cam retard. It took awhile to figure out all the technical stuff. (Dealer wanted $200 to set it.) I was close at 8.3 degrees. Got it set to 0.0 at 1150 rpms and finally buttoned everything up. The truck runs like a dream! So much more power than I remember. The injector timing being dialed in really opens up this big block. It’s like a completely different truck! Thanks again for all of your input in helping me solve this issue. Helps to have forums like this one! Cheers.
