Is this a matter of getting them to shakehands or reprogramming because the new turbo has different characteristics.
I could see the point if reprogramming is required. Hard to see a defense if it's just a matter of getting the new turbo to shake hands.
The issue is getting them to shake hands. And yes, the manufacturers are fighting tooth and nail to avoid being forced to allow non-authorized handshaking. There is a lot of money involved. My wife's Subaru didn't come with remote start, so I got the factory remote start kit and installed it. I bought it from a Subaru dealer in Massachusetts and installed it. Then I had to take the car to my local Subaru dealer to have it "turned on" which took a total of 10 minutes. The charge was $150.
