I don’t think it was removed altogether from the model years. It came down to whether or not they had the chips at the time your truck was built. If they forecasted that they would not have them they gave you the option to delete it and have the truck built faster. My 2022 truck has (had) it from the factory.
Gotcha. Neither of our 22's have it. I am not familiar with the Gen 3 cobb stuff, I did use a cobb tuner briefly on my Gen 2.
I would be curious if you could turn it back on with Forscan, as that's what I used to turn mine off on the Gen 2. I wonder if it's a deal that you can turn it off with the Gen 3 cobb but have to turn it back on at the dealer or with forscan? Might be worth a call to cobb.
Either way, I had Phasers done on the Gen 2, cobb hadn't been installed in some time, but I did have a bunch of forscan changes that stayed after the repair. No mention of anything from the dealer about it.
