I forgot to "uninstall" my cobb tune from my 2015 subaru forester XT. It wasn't anything crazy but did improve the day to day of that vehicle. Well I was like OH i have the cobb tuner and all , maybe I can use for the ST when I bought it. Nope Cobb refused to budge coming down like $100 if that for a ST tune because I never removed the tune from the XT.
They were kinda pompous about the situation if you ask me. The vehicle was 9 years old at that point. Not like I'm trying to scam was an honest mistake.
But otherwise yea, there are licensing considerations with the tune you want to think about if you plan to use that same firm for instance, that is the take away here. On top of that , it would be a dick move to sell a vehicle for instance with a 93 tune and the new owner doesn't know or care about it and grenades their motor.
