Sounds good...I noticed that the Dodge tuners are less expensive than the GM one. My guess is the GM license costs more than a Dodge or Ford license

I have a 2015 Tahoe 5.3 and a 2012 Dodge Charger police car.I want to be able to use one tuner for both cars. If i wanted to buy a tuner with an additional license, should I purchase the tuner for the GM product or the Dodge? Thanks, Tom
