L96 issue *stuck* Heres the scoop- 2013 sierra 2500 w a L96.
throwing these codes -
p0341- CMP sensor
p0326 -knock sensor
p0101-MAF sensor
I have replaced - MAF sensor, Cam sensor, timing chain, guides, crank and cam sprockets, VVT solenoid.
timing is good.
when I go drive it it lacks power and the computer reduces power drastically.
not sure what else I can investigate

You may have a wiring issue then. Are you in the rust belt region? Maybe a ground having too much resistance? The various grounds are sometimes issues depending on location in the US.
You most likely don't have sensor(s) issues since you already replaced them. Hook up a scanner with live data and see if the values reported jive. Like MAF values should be 6.0 grams/second in idle. Do values increase as you give it throttle?
I don't know if you have to do a crank sensor relearn on that engine?
