Default cam / crank sync

I have a 2012 Ram 2500 4x4 5.7 auto . For past month I have been chasing a bog that I have down low in the 2000 to 3000 RPM range .And a slight extending crank on cold start up . I have no engine light and no codes . I replaced the spark plugs and the MAP sensor but no change . I did notice that on my scan tool under data . It says cam out of sync , crank out of sync key forward engine not running . when I start the truck cam data says in sync but the crank data still reads out of sink . I replaced the crank sensor and did the cam / crank relearn . Still crank reads out of sync , still have extended crank when cold , still have the bog . The truck is pretty much numb with no power under the 3000 RPM range . Its kinda like driving a 2 stroke once the RPMs come up over 3000 or so then the power comes right on and truck pulls hard with lots of power . Any body have this problem or have any diag or tests I can do to try and figure this out ? thank you !

I repaired an 11 hemi few months back now similar symptoms but this truck was setting a cam/crank correlation code. Screens ended up being beat out of the oil control solenoid for the cam phaser.

I have been thinking about that also . My truck does have 125,000 on it . But has always had oil changes at 5000 miles . I replaced the cam sensor yesterday and did the relearn for cam and crank , it says relearned but still reads crank out of sink when truck is running while watching data . I have also tried 2 different scan tools . Its kinda frustrating , i am a third generation auto tech and i run a garage in NH . So i will figure it out at some point . I wish i knew someone with a similar truck so i could see if there data is the same as mine . I did talk to my brother who is a tech and runs a different shop in the area . we are gonna get to together and drive around and watch and record data when the bogging happens and see what we can maybe figure out ! Any idea at what RPMs the cams should advance ? my truck is kinda low on power till about 3000 RPMs and really turns on hard at about 4000 RPMs . another thing i should add is if you just mash the gas pedal to the floor from dead take off the truck rips with no real bog or almost not noticeable .
