HP Tuners eliminated model year licenses on the Gen 5 trucks. If you are really tuning 50 vehicles a year (really tuning) you should be using HP Tuners. If nothing else for the better scanning. Add the license cost to the cost of the tune. After you do a certain number if individual licenses for that vehicle type and model year it converts to a model year license on Gen 3 and Gen 4 trucks and cars. Even when I use Tunercat OBD2 I still use my HP Tuners for scanning.
