What happens if you don't change the cam phaser?

I was going to make a new post, but I was not sure it was related to not changing the Cam phasers. So, responding here.

Anyway, I had the Cam Phasers rattle for a while, keep putting it off didn't have another vehicle at the time. Then my Truck started at high speeds 80+ or going up steep hills or towing something heavy doing what I would call a "turbo surge". It's like if you keep pressing and letting off the gas and you could see the Turbos gauge moving up and down. (Side to side I guess on the cluster). The truck was also acting like you were moving your foot up and down on the gas pedal.

My Mechanic buddy said something about the cam phasers and timing and that was messing up the controller for the turbos making them surge like that? I had him ride with me. Sorry I don't speak Mechanic.

Anyway, I took in to have the Cam Phasers done told them about the turbo problem and they said it could be related to the Cam Phasers but would look at it. They replaced the Cam phasers, and it looks like it fixed it. 4K miles in and my truck runs great. No Turbo surging.

2019 100K plus miles and Goose Tuned.

Nice, great info thank you. Found out mine had the recall implemented so should be calibrated correctly now

That’s literally the entire point. Without the new calibration the phasers will wear abnormally and eventually fail, regardless of what part number is installed.

Whats the fix for the many trucks that have had to roll back the calibration for issues?

What kind of expense do you think will there be for the new calibration?
